Car had little to no power, changed both cat $600 both were shot. Changed plugs, wires cap, rotor, power pack, fuel filter, maf and map sensor, radiator (defective). Car ran great for a week like new and then died wouldn’t start. Called a friend who is a mech. At first he said might be spiders now he says after testing it's the fuel pump. Would a bad fuel pump cause erratic starting and rough idle when it did run. Also could a bad fuel pump effect the spider. One more item oil seems to be hot, when I check the stick a white mist emits from the dipstick tube. Oil has no gas smell and no water present either. What the hell is going? Any insight is appreciated.

 

Well, i would check the fuel pressure before i spend any money like i did !! I replaced the spider to the new style and it runs better but i have a stumble and rough idle when warm !! i have a reading of 52psi running and 54psi with key on engine off!! I should have a pressure of 60-66psi with key on not running !! So check first .... not sure about the white mist but hopefully its not antifreeze!!

 

I second that. Go get a fuel pressure tester and check your pressure. It if will not hold pressure when not running, it's probably your spider or your fuel pressure regulator (mine was the regulator). If it is poor pressure throughout, most likely cause is the fuel pump. Shame you don't have my intake plenum, I could peek inside and see the leak.

 

changed my spider an now its niceeee... dude go for it..

 

They check the fuel pressure and there was none, so they replaced it for $465.00. Now the not so funny part they still can't get a reading cause there no juice going to the new pump. They have to drop the tank again because they didn't change the wiring confiuration for the new pump. Hope I didn't waste the money on a pump (even though it looked like crap) When it may need a new spider. If it was a horse I'd shoot it. But I love that car.

Thanks I'll keep you and the others posted

Spoke to someone that was there who told me the pump they put in was a Delphi and defective, so they had to drop the tank to redo besides. What a crock of BS. If it is the intake plenum anybody know the proper brand to get, That I’ll do myself. I’m about to lose my temper. Great Truck otherwise for the 136,000 mileage. Like the old saying “cheaper to keep her than to get rid of her” Plus I’ve grown attached to the old girl.

Thanks guys

 

The intake plenum is the metal part of the engine your throttle body connects to. Mine (1995) has a different looking intake plenum where you can easily access the inside for a peak at the spider.

Cars running great has power, runs almost like new. New Fuel pump. put Seafoam in what a difference. Now 156 miles later Im pulling a p0440 code what the F---. Any Ideas? can I make a smoke machine to see if there are any leaks and if not do you know what it cost to smoke the system?

Thanks

 

You made two pots about this same issue, please dont re post the same questions. but like everyone above was saying, and also saying in your other post. get a pressure test done on your fuel system, then if you get good results from that (60+ PSI) then you need to start checking the pressure in your cylinders.

 

Seafoam kills spark plugs. I learned this the hard way. Replace them after every use. Not sure if it is your problem, but it's due diligence.
