i have gone through my entire engine and replaced everything lower intake gaskets,upper intake gaskets,6 fuel injectors,throttle body,pcv valve,egr valve,egr solenoid, idle air control valve,throttle positioning sensor,4 o2 sensors,2 catalytic converters,1resonator, plugs,wires,plenum gasket,dpfe sensor,maf sensor,air filter,vacuum lines all 27 of them, and still my car is acting up before it would start and idle poorly then it would die after dropping below 500rpm then after alot of replacing of parts it started fine then i shut it off went to replace a hard line vacuum line that connects by the brake booster line that hooks into the intake system got it replaced only to find my car wont start now i am so done with this does any body have any logical explanation for this but the best part is i dont have any codes at all it just doesnt want to start and i need my car by february i start college on the 15th

Sounds like you need to stop parts swapping and have a technician take a good look at it. The AutoZone method of repair hardly ever works (code pops up, replace the part). You probably could've paid a tech less and replaced far less and had a good running car...

..back to basics here.Check for fuel pressure in the rail and then check for spark...As you have had so much off I'd check ALL the electrical plugs that you disconnected...those on the belt/timing cover end don't always click/lock and make full contact,also the large squre plug on the drivers side inner fender with the 10mm bolt...Recheck all of them first..then go to fuel & spark...

dom i own my own snap on code reader and diagnostic machine i use to work for a shop and made a carrer change but kept all my tools and machine's all those parts were original and the engine had 132,734 miles on them so i can see how they were coming up as bad, after you had mentioned gaskets that may have been torn i went back through and you were right i had pinched my upper intake gasket so replaced it and since then my car has ran perfect it idles at 620rpm's so thanks for all the helpful input you had


and terry it has 41psi on the fuel rail and all connections are fine but have found out that my car is known for having a bad wiring harness so i am buying a new one and putting it in at school

[Terry Haines]

...I doubt you will find new harnesses for the engine.Most all that go due to bad insulation need to be rewired etc and it's a damm pain!!

[Adam J. Owens]

oh crappy i found one on ebay so now that you mention that terry i will just rewire the entire car if there known for having bad insulation well atleast it will go towards my grade haha
