So why did you replace the pump in the first place. What is the fuel pressure? what should the fuel pressure be? Do you have spark at the coil? do you have spark at the spark plugs?

I Let my chevy Blazer run out of gas,nw it wont start even though the relay and fuelpump is working.


Is it electric or mechanical pump? Electric is with fuel injection. If its fuel injection, you should hear the pump run when you turn ignition switch. If u don't hear it, try starting, if no, turn off then on. It will self prime. Carburetor is with mechanical pump. I usually put few drops of gas in the carb. Start it, if no, more in carb till it stays running.

2002 blazer crank but wont start


2 things that you have to check on no starts every time. Spark at spark plug and fuel. Turn key to run position and listen at gas tank for fuel pump to run you should hear a whining noise. This will only happen for 3 to 4 seconds then it will shut off until engine starts. You can turn key off then to run every 3 to 4 to listen for fuel pump. You may hear the relay click off in engine area even if pump does not run. Fuel pump failure is pretty common. If pump is running pull spark plug out or put a spare plug into spark plug wire and have someone crank engine set plug on engine and watch for spark. This will give you a starting point. Hope it helps.

1994 S10 Blazer Fuel Issues?


are you sure the pump you installed is not defective it does happen more than you can believe. If you can run a power to the pump hot line or jump the relay and have a ear to hear if it is pumping, this is what I would suggest.. Good luck

Wont start


The fuel pump will run for a short time when you turn the ignition key on to prime the line then waits until the engine is running. Check the fuel filter and replace if plugged then check the fuel pressure should be abouve 27 psi

1999 blazer wont start??


Your battery is either faulty or ther is a parasitic drain, have it checked out at parts house. With a good battery installed, spray some starter fluid into intake housing. If it starts, then dies, you have fuel pressure/delivery problems. Can you hear the fuel pump run when you turn on the key? Hope this helps.
