ya injectors are new neon ones.
if one of them is leaking that could be it.
so maybe one of the new ones is seeping...

didnt know about the FPR i may have to tinker with that and see what gives. could be dumping more fuel than it needs to be.

Thanks for the input guys

 

Great story Lykos^. (Golly, guess I'll never get a Monte Carlo), And welcome! Not following myself exactly how a leakdown is going to help find a fuel leak though. (fuel will run past new rings too)

Mopar, It looks to me like he was talking about himself.

When I had an injector or two bleeding off the system pressure when the engine was off, it would miss and stumble for a few seconds on a warm restart. You might try letting is sit a few minutes hot, then start it without revving it or touching the petal and see if it misses.

I suppose a pinhole in the FPR diaphragm could let fuel in. Would expect a manifold full of gas to flood it starting though. Then also if you were topping off the tank, fuel could "find egress" through the evap system. Injectors.

 

The FPR on a '99 is part of the fuel module in the tank. I would pull the fuel rail with the injectors and turn the key on and see if they leak.

 

appreciate it.
ill try that this weekend as im not driving it at the moment.

i do know that everything fuel hat wise in the tank has been replaced about a year ago by PO.
he ordered a whole new fuel hat... wondering if the FPR came with it on that... maybe just since it's new its putting those injectors to the test.

but ill def pull the rail and check it out.

thanks

 

Thanks fishtaconc. Yea, "one liners".

 

Yeah, so I was indeed referring to myself as a Noob.
