Starting issues - No / Doesn't / Won't Start - MERGED

[prodsm]

All "my car won't start" discussion threads are merged HERE. We've basically made it easier for those who insist upon not searching by grouping together all threads from those with similar issues so you can just scroll through and see some possible solutions. To search for info within this thread, use the "Search This Thread" feature in the black bar about 3" above what you're reading right now.

Could be anything from a loose battery terminal to internal engine damage, and literally everything in between which may involve the electrical, fuel, and ignition system...possibly even something that you screwed up while working on the car yourself. While it's unlikely we're going to diagnose and solve your problem over the internet, feel free to discuss any possible solutions.



I live in Canada and right now its not very warm out, about -30c
my car does not have a block heater too keep it warm.

I tryed to start my car this morning and it wouldent start, ive had this problem before but this time, the car doesnt crank at all it just makes a sound that sounds like an electric drill.

Whats wrong.

Thanks

This is a new version of a no start. long story short i was doing alot of rear rocker panel restoration and no disconnecting the battery when welding wasnt that smart. overall the car has power but wont crank at all?
how do i figure out my issue , starter? igniton?ecu?

 

[1Gina2G]

are you sure your battery isn't low? do you have a volatage meter? if so meausre voltage, plus or minus 12V is normal with the car off anything around or lower then 11V could cause a no-start issue.

Check your relays. If you have an aftermarket alarm system it could be causing a problem where its tied into the ignition system. A relay is getting hotter everytime your car starts until it gets too hot in which it cannot function properly.

Something could of fried. Check to see if you are getting power to your starter when you turn the key. I don't know about on a car but our cat motors computers at work will fry if you dont unplug them before welding on the motor. See if you can smell anything burnt and check your fuses. That's where i would start.

 

[northernawd]

check all your fuses and try knocking the starter possibly? clean your grounds and make sure the connection is tight.

thanks man i will look at my relays !

its probably your coolant temp sensor.

^ The above post might be a good idea, the starter silenoid could be stuck; take a hammer or large screw driver and tap (keyword: tap) it. Also it's possible that you've fried something as a result of welding. I would start poking around with a voltmeter if I were you. The 95-96 Electrical Factory Service Manual might be of some use.

Check your grounds

 

[heller34]

Could be either the starter or the ecu. i would put money on the ecu but i had a starter go bad on me once too so its hard to say which.

I'm helping a friend with his 90 GST. It's a 6-bolt with 2G Pistons and has about 2,000 miles on it. Car was running great until about 8 months ago the Timing belt tensioner failed and it jumped time. He was actually able to drive it home and it was only 1/4 mile from his house. It ran like it was on 3 cylinders. We tore it down to have the head checked and of course it bent some valves. So now 8 months later he finally gets the head fixed with new valves, seals etc, new head gasket kit, new oem timing belt tensioner, oem timing belt and we got the car back together. Now it won't start. It has fuel, spark and timing is dead on. CAS isn't 180 out either. I pulled the plugs and they're soaked with fuel. To me the gas on the plugs didn't smell very strong. Anyway, I did a lot of searching/reading and decided to replace the coolant temp sensor. Still no start but it did come close a few times. Pulled the plugs and 2 were dry but the other 2 were wet with fuel. Did a cold compression test #1 80 2#78 3#80 4#76. I know thats low but i'm hoping thats from the fuel washing the cylinders out. When you look into the spark plug holes you can see a puddle of gas on top of the pistons. So next possible issue, He filled the tank up with 93 octane 8 months ago and both fuel lines were disconnected until now. So I'm wondering if leaving the fuel lines disconnected for 8 months can allows gas fumes to escape? Any suggestions or info would be greatly appreciated. Thanks

it's not my temp sensor because i just fixed the problem with that were do i find the fuel relay ??

i get it to run but it sounds like it is not running right like when i turn on my head lights my rpm will drop way down and come back up i know its not the bat or the alternator because they are new . and when i shut my car off it wont turn back on till its cold again and when i crank it it sounds like it is cranking really fast well at least what i think. can some one help me out please !

 

[daplatano91]

When the car is hot and dies, does the rpm gauge move while it is cranking?

yes but not much.

Please people quit blaming all this no start bs on cts's. This is not even close sorry. Cts would give cold start issues not hot. Think before you post. And fwiw bad cts causing no start is usually pretty rare. Go unplug yours and see if you can start your car.


Op, your looking at a sensor issue IMO. Sounds like your CAS is going bad.
You should try and test it when its not starting.

 

[daplatano91]

Grab yourself a can of brake/carb cleaner and when the issue presents spray down the CAS and try starting the car. The CAS may be failing when it gets hot.

Why do we all have to line up? Do we only get to rag on your homophone confusion one at a time?

 

[tkstoygsx]

I didnt see an answer to the "Did you remove all your emissions" question.. also, what are your mods?

 

[miguelmcv]

A bad cooling sensor will make the car not to start, I have experience it, so I know from first hand,,,,, I can even unplug my sensor and the car will not start, However, I don't think a cooling sensor will do that problem that the OP has.

To the OP,

When the car warms up and doesn't start, check your Transistor, It could be your transistor is bad, once it heats up it doesn't work,. Check if you get power at the coils, if you don't have power, then your transistor or CAS is not working, But I will lean more towards the Transistor, which the cas will produce a misfire and or will not work at all.

 

[arabeclipse]

I had the same exact issue. Check your maf. That was the culprit to my issue.

 

[mark 91 tsi]

I would start by drying the gas out of the cylinders, drain the fuel tank and lines if you are not sure of the fuel condition, and replace the fuel filter. Put some fresh gas in it. That way you know you are starting from a good point. Good luck.

 

[Diamond Star Werks]

pretty rare.

rare not impossible. There could be other issues that helps your car not start cause of it. I know mine will cold or not. Not argue as i said it is rare not impossible. Its just I keep seeing ppl say that so much, almost like crankwalk.

Im aware it does start but there is a lot of information there to help. Youll find out you may not find the exact answer to your questions so many variables. Some questions you get exact answers and others not, i see a lot of that when others say thats the not my exact problem. Every little bit helps.

 

[erkitner]

I don't see why you ask about gas fumes. The fumes have no bearing on whether or not the car starts. In any case, your car does have an EVAP system which already lets the gas fumes circulate to the intake of your engine. So again, no relevancy there.

Although I hear everyone say that the timing is good, check it again. Then triple check it.

Back to basics, verify spark, verify compression. It'll hit you like a train when you figure it out. I wish I could help you out more but it seems pretty basic for me, based off the info you provided.

I also don't think 8 months would foul that gas out.

Oh. AND those compression numbers? SUUUUPER low. I just did a build with 180 across the board. Look up what you need to be indicating and base your diagnosis off the raw numbers. Sometimes, you don't like what you see, but... then again, we ARE dealing with the Devil's Diamonds.
