Long starting time?

Postby kurto_15 » Sun Nov 11, 2007 8:56 pm

I have a 1991 Chevy C1500. The past month or so it has taken a long time to start. It turns very quickly so I'm pretty sure its no the starter and the battery is good and I can here the fuel pump. What do you guys think is the problem?
Thanks in advance

If it is turning at the right speed and you knwo for a fact that yoru battery is in good shape, my first guess would be a fuel pressure issue. The chevy trucks were known to have fairly predictable fuel pump problems. I have seen the pumps get "weak" either int eh fact that the motors current draw goes up or to the point that the impellers is worn, crack, or broken to the point the flow is down.

A quick way to verify my guess would be to cycle the key 3 or 4 times before yous tart it. Jsut turn the key to the on position until you hear the pump come on to prime the system. then turn the key off and on again. Repeat 3 or 4 times. Then if hte truck starts normally without the hesitation, you have a fuel problem. If not, keep lookin!
Shoot'em close. Less to pick.

Whens the last time you have had a good tune up? After you do the fuel pump thing check your spark plugs, wires, rotor etc.

Well I replaced the fuel pump and rebuilt the fuel injector pressure regulator. That didn't work. Any other thoughts?

Thanks

Change your spark plugs, check everything for corrosion and make sure you got good voltage.
