Hi! So about 2 months ago my fuel pump went out. Had it replaced and right away we noticed sometimes it would crank but No start. After a few days the pump was defective, so replaced it again. Pump ran great with good pressure but after about a week or so, same issue crank but no start. Sprayed some starter in the manifold sometimes start, sometimes no. Turn key on/off to cycle and then sometimes start, sometimes no. Used the pressure valve behind the spider to bleed air/fuel then engine start fine. Would run fine for a couple days up to a week and then same thing all over again. Took it to local chevy. Diagnosed fuel pump, ... good to go they said, everything working properly. 2 days later No start and this time cannot get it to turn over, pressure is at zero. Pump is still turning on but not humming like it was. Replaced MAF and distributor cap as well as fuel filter. My local mechanic and I are stumped, and I'm already $1000 in on repairs. Please help! -
I have a 1990 Chevy K1500 5.7L 4x4 pickup that cranks but wont start. I can get it to start by spraying starter fluid in throttle body but only for a few seconds. The fuel pump was just replaced in October of last year. I can hear it click on when i turn the key. I haven't checked fuel pressure because I cant afford to rent on for $160. Could my fuel pump be bad? Or fuel relay?Incidently this 350 motor is a swap I got to replace my old motor that that went bad. Truck has run since motor swap but only for a short time. Then file pump went out and I replaced it back in Oct. Any help would be appreciated.. Thanks.. -
Hi, first I need to say at everyone that I'm French and my English is bad ?. I have a chevrolet 1989 C3500 with a 7.4 engine. I drive on the highway when my truck stop like if I turn the key off. The two tank was full of gaz, I start and the engine crank so the gaz doesn't run to the throttle. Someone has the same problem in the past and can help me?
