Ive had a mechanic look at my van and he said it was way out of time. So I had him replace the timing gears and chain. And I drove it home. But now it will not start at all. After discussing the problem to the mechanic again now hes saying its the fuel pump, but I can hear the fuel pump running when I turn the key. Is there anything I can do myself to try to problem solve my issues?

i once had a ford that had a switch for the fuel pump. But even then it wouldnt make a sound when I turned the key on it till I reset the switch. Is this van equipted with such a switch?I dont have an owners manuel I bought it used

The above link may have your owners manual, it's free. Type in year--make--model. There is another web site that has GM owners manuals online. gmownercenter.yahoo.com, something like that.

I'd use a fuel pressure gage before I suspected the pump. Some of the national brand auto stores used to loan out a fuel pressure gage. There is no fuel pump shut-off switch, if that is what your talking about? If you have the 4.3L engine, fuel pressure is 60--66 psi.

Thank you for the information. The fuel pressure was too low

now the engine is starting, but when I accelerate it dies.

Ive replaced the plugs, wires, cap, rotor, coil

might you have any suggestions on the cause of this new problem

Low fuel pressure might cause that. If you have the spider fuel system, the fuel poippets may need cleaning, if it is a fuel issue?
