Hi everyone,

Im a corvair guy and have some general automotive knowlege but I thought I'd ask you all for some help.
My brother has an '88 Iroc with a 350. Hes been driving it for 3 years now, no problems. Just last night after getting gas, it barely started and wouldnt run without having to keep your foot on the pedal. After 5 minutes on and off, it ran fine, and he drove it back to the house. Today I drove the car around the block and it was running kinda rough again but not as bad. As soon as I pulled it into the garage it sputtered and died. It will not start, wont even pop. Must be fuel or spark because its definitely getting air. I checked the spark by pulling the plug wire off the #1 plug, sticking a screw driver in the plug wire end and holding the shaft close to the exhaust manifold. I had someone crank the car over and I saw a nice bright spark. So the only other thing it could be is fuel. I sprayed some starter fluid in through the throttle body and the car started right up and quickly died.

After talking to my brother I found out he replaced the fuel filter 2 months ago so a clogged filter is out of the question.

What is the most probable cause?

Thanks,
Wyatt

 

just for the hell of it--did you check your fuel pressure?
First it sounded like your iac had to be adjusted until you said it doesn't even want to start--doesn't even pop.
Any headway yet?

 

wcirco did you find the cause? I have a friend that is having the exact problem!
Or if anyonw eles reads this and has the TPI 5.7 350 motor and knows what the problem could be. He has spark.

 

Ohm your injectors first, then check fuel pressure. Its easier to ohm inj's, thats why i said do it first. If it started with starting fluid but wont start on its own i think it is safe to say your problem is lack of fuel. You can ohm them, but also use a stethoscope to listen to each inj to make sure it is/isnt working.

Are they the original Multech injectors?
