I drove my 94 Z28 last night, only problem I had was something I've been dealing wiling for a couple months. I had a new starter put in but the heat shield is magically gone causing the starter to not engage when it gets hot. I'm used to that and have found a way to start it by moving the ignition switch back and forth to get it to engage.
Today is something different though. I went out to start it for the first time today, it engaged and sort of started them died. Now the starter just tries and tries to start it, it sounds like it may start but will not. It's chilly here, 39 degrees, and I have a good battery, starter is 3 months old.
It's getting power but sound like its not getting fuel. I don't smell anything and left it to sit for 4 hours and tried again, same thing. The starter is engaging, car is not starting.
Thoughts?

 

*dealing with. Darn spell check...

 

got gas, test fuel pressure. change fuel filter.

 

Give it a shot of starting fluid. If it fires up then quits, it's a fuel issue. If the engine doesn't pop at all, it's ignition related.

 

Turns out it was a vacuum leak which caused it to flood with gas. Took out the plugs, checked the compression, gave her a tune up and she's all good.

 

A vacuum leak causing it to flood? I did not know a fuel injected motor could flood? Can a vacuum leak result in running rich then?

 

Yep, if it's tied into the vac line that goes to fuel pressure regulator.
Vacuum to the regulator is what opens it up and sends extra (unused) fuel back to the tank. With no vacuum to the regulator, it's not opening and bypassing, and you'll be pouring way too much fuel into the engine.

 

Hmmm...maybe something to check for my running rich issue.

 

Worth a look. Pull the vacuum hose off the regulator, look for and smell for gas. When the regulator goes bad, the diaphragm inside tears, and gas goes where it's not supposed to.

 

And d@mn if I didn't go to pull the vac hose off the fpr and it came out in two pieces, apparently was cracked and just broke, it's real brittle. I fixed it temporarily....We'll see if it makes a difference tomorrow.
