Getting no spark on plugs.

[Skillz]

I don't really consider myself a 'noob', but I think this is a easy problem, I just can't figure out the solution.

I drove my car to work Friday, at 7 AM. Got off around 3 PM and got in car to go home. Car would not crank. First thing I did was check the gas, it was very low. So I figured I was just out of gas, put $5 worth of gas in, and car still would not crank. (I cycled it, so that I could get gas to the engine. (Fuel gauge should that I had fuel pressure) I then proceeded to think that I was not getting enough volts from the battery, so I had someone attempt to jump me off. That did not work. So I check all the fuses under the hood, and under the dash. None was broken/damage/unplugged. I then asked a friend to crank car while I held a screw drive in one of the plugs, to see if it was getting fire. And nothing, I tried the #1, #3 and #4 cylinder. Still no go. I think broke out the book and checked the cam angle sensor, wiggled it a few places and still did not change anything.

My question is, what else do I need to check/look for?

PS
I also changed the coil packs with the one from my FWD Talon, which I know are good. Still did not work.

I have an Apex Turbo Timer, and the GM MAFT installed on this car. So keep that in mind if you can think of a solution.

Thanks,
Skillz

::EDIT::
Almost forgot.
It's a 1991 Eagle Talon TSi, AWD.

Distributer?

Well;

If I had a distributer, then I would have changed it instead of the coil packs. I have the 2.0l Turbo Engine, it doesn't have a distributer, like the 1.8l engine does.

To answer your question though. I swapped coil packs with my other talon, which I know are good. Still no cranky.

haha I didn't even know our cars didn't have distributers. I've never really looked for one before. :laugh:

You'd actually be suprised at how many people don't know that; then when you tell them it doesn't, they get all offensive and start saying stuff like (cars have to have distributers...) and such.

Still wish I knew what was wrong with my car though.

Try pulling out your MPI fuse and turning the car over a few minutes, then put the fuse back in and see if it runs. Sounds like you maybe getting to much fuel to the motor, just my .02 though, later.

Hey, I know where the MPI fuse is, but would you happen to know what it is for?

Also, if I am getting too much fuel to the engine, would that cause me not to get any spark on the plugs? Going to try that out right now though!

Thanks!

Do elobrate on this. What do you want me to do with it, and exactly where it is located? (Guess I could look in the book...)

It's connected directly to the coil pack.... the power comes from the transistor, into the coil pack, then from the pack to the wires, wires to the plugs. You may have to replace it.

Do you throw any codes? There is quite a few things it could be, crankshaft sensor, cam angle, power transistor, ecu, fuse/relays

this would be my guess...i had the same problem last week, make sure its not blown before you put it back in

The plug, or one of the bolts that hold the coil pack in its place? (If its one of the bolts, then I am an idiot!!)

Also, I don't think the car is throwing any codes, doesn't it have to run before it will throw a code? If not, how can I tell. (I have the pocketlogger, but I just got that and the car last week, so I am not 100% sure on how to hook it all up. pocketlogger's batteries was dead, so I will have to reinstall all the software (I have them on CD))

Thanks for the help guys.

PS
I remove that fuse, let it try to crank for like 30 - 45 seconds, then put it back in and tried to crank it, still no go. (I think my battery is dieing, I noticed that it now dips to around 8 volts, while I am trying to crank it. 11.5 ~ 11.7 while it sits.

It's where the plug from the coil pack goes to. It's not a bolt, it's a little black box.

I'll post back when I find a pic.

In this picture, the black-boxish items to the left of the coil packs are the ignition transistors.

ya that..... and uhmm.. do ya got an extra ECU you can swap in as a test?
Are you sure your cap's arent leaking?

The MPI fuse is for your fuel. If you are getting to much fuel it is probably puddling up on top of your pistons and believe it or not can actually putting out your spark. For the record you really can't use the old screw driver method with these cars for some reason, unless you put a plug in and lay it on the valve cover and have someone turn the motor over to see, BE CAREFUL IF YOU TRY IT THIS WAY, make sure there is no gas or oil near by, later.

p.s. If you need a coil pack I have one laying around here somewhere, also check the wires on your translator for any that might be loose or not connected.

i wasnt getting spark on mine when my mpi fuse was blown... i cranked it a few times with no fuse, then replaced it and it fired just fyi

 

[Skillz]

I removed the MPI fuse, and tried to crank car for a few seconds. Then I put fuse back in, and still no crank.

I have an extra ECU in my FWD Talon. I will swap them out tomorrow, it's too cold and too late right now. (Plus, I don't have my tools.)

I do not see why the screw driver trick wont work? I will attempt the spark plug suggestion tomorrow also, just gotta do it on the left side of the motor...gas is on the right. Long story.

I also swapped out the coil packs with the coil packs in my FWD Talon, ones that I know worked, before the tranny went out. (Which was like last weekend sometime)

Thanks for the help guys, I will keep everyone posted on the status as I try the suggested methods/solutions.

Oh, I also accidently blew the radiator fan fuse, on the battery it self. Spent like 45 mins trying to get that thing off, before realizing it was bolted on. I thought that once the amps get over 50, the bolted them down. Not 30. I know the Alt fuse is bolted down, had to change that one also!
