hard to start cold 1995 GSX

[billk1]

Since it got cold out my car has had a hart time starting when real cold-teens or lowwer, fuel system good, holds 45 psi for days, newwer filter too, on single digit days it took 20 trys before it starts to pop, mostly happens overnite but even on 10 hour periods, swapped coolant sensor but no difference, also noticed that when it does start after a hard try, wideband reads 15/1 for a few seconds then drops to 12/1 for a few seconds then rises up to 14.7-15/1 and no idle problems, what else should I check-MAS?

I've got the same problem up here. Check your battery voltage. I bought a battery and oil pan heater so it wouldn't lose so much juice overnight.

Can also be that your battery discharges quick in cold weather.
Or that your engine might be to cold to start right away.
Checking the MAP can't do any harm either

I had a vacume line on the right hand side(looking from the front of the car) that went to the intake manifold that kept coming off. Its supose to keep fuel in the lines when you shut the car off. Just something to check.

It cranks with no problems, just doesnt fire up, im going to check spark output first to eliminate that

How old is your battery?

 

[Clinical]

Check battery, what kind of gas are you running?

my car is much worse, takes me about 5 minutes of trying to get it to start to fire... damn you e85

Im in the same boat as all of you guys when its cold out its will crank over easy but no luck on starting. the code that i keep getting is coolant temp circut malfunction and egr circut malfunction i tested resistance on the temp sensor and it was good but i kinda wanted to check other things before buying a egr valve oh and the circuts seem intact no opens i dont know what to do??

I got the same thing going on. I ended up replacing my battery with an optima red top, and it still does the same thing. It's not as bad now, but it still hesitates to start in the cold. I'm at a loss for what going on... but I'm also not gonna bother with it until the day I need a jump from draining my battery.

just running 93 oct. I do have thr egr removed and blocked off,cel lite no hooked up- wonder why!

hey, is the check engine light harness on the 95 the same as newer DSM's?

Still no luck on this problem, didnt seem too bad, if above 0 degrees it could take 10 different crank cycles, but today was minus 10 and she wouldnt pop, I had a battery charger on it over nite cause I new I was going to have some fun in the morning, engine turns over fine but doesnt fire up, I have 2 fuel gauges and both show high 40s before and after cranking, my 255 pump starts when I turn the key on , I put a spark tester on each plug wire and all looked good and even pluged in the sparkplugs and grouned them and they all lit up ,I pulled the plugs and I first thought they were flooded but when I took a close look at them there was some ICE on them, how would ice form on a spark plug?I always buy good premium fuel, newer gas filter,they were bpr7es so I went and put some new bpr6es in and swapped a coolant temp sensor in it and tried to start it and no change, I have a used AEM ecu that I wanted to swap in some time in the future so I put that in to see if it would start but still no pop, put back old e-prom ecu but this time temps were aroun 10 degrees and I sprayed the load of start fluid into intake pipe and she kicked over and started up, seems to me like some fuel enrichment problem, any sensor other then cts I could check?

Battery/Coolant Temp Sensor, U should replace both.

Battery/Coolant Temp Sensor, U should replace both.

Battery is a good red top, Looking into sensor wiring, when I unplugged CTS ac fan started running so sensor is not open and I did replace with 2 good sensors so back to checking wiring to ECU
