fuel pump?
Dear Friends,
I have a 1994 C4 that does not want to start. It always popped off right away and last year it would spin over a few times before it would start when the engine was warm.. First cold start it would still pop right off.
Now it will not fire. I tried starting fluid and it would start and die. I put the fuel pressure gauge on it and it does not register any pressure. Seems like a fuel pump to me. The car has 60,000 miles.
Can anyone offer a suggestion? Thank you kindly!
Greg

Fuel Pump Question
Apologies for (sort of) hijacking the thread. My 95 is having issues starting, and I’m thinking I have a pump issue. Key on, not running, pressure goes to about 42 psi, then after 3 seconds, when priming stops, pressure drops immediately to around 5 psi or less. I’ve read that there is a check valve (ball) in the pump to keep pressure up. Is there a way to diagnose this issue?
When I do get the car to start, pressure is about 32 psi steady. It idles rough, and misfires during acceleration. Any thoughts would be appreciated!

Change the fuel filter and see what you get.
