CAR PROBLEMS

i had a buddy that works at the local Cadillac dealer come on over so we can take a look at the riviera, and he had me try to start it with the fuel pressure gauge and it read 29-30 PSI what could be wrong with it and what parts do i need

Try reading it under load at WOT.

you should read it with the engine running and vacuum gauge disconnected from the fuel pressure regulator. At 30 psi it should have enough fuel to start, I wouldn't count it as low fuel pressure unless you are at operating voltage (engine running).

the 30 PSI was at WOT

come to think of it, I keep forgetting yours is a '95 (you should keep that in your sig somewhere). I don't know what FP should be on a series I.

FP is 43-48 supose to be,

i will fix the sig

fuel filter been replaced?

yupp

should i just replace the whole fuel system

I had the same problem, not enough fuel pressure. After I changed the fuel filter and still had the same problem, I added a hp pump and it took care of it. I will check with my source to see if you can use the same pump. It is made for a GTP and requires a little modification.

You will want a little more umph if you plan on modding... I also went with a hd wiring harness which was easier to install than the pump.

were can i get one

Racetronix is the manufacturer. I believe my source got it from Intense but I will check. Let me see if it will work for series I before you get anything. I'll do it in the morning.

BTY... are those wheels photoshopped on your sig or is that what your cars wearing? I like regardless...

According to the FSM pressure should be tested w/o the motor running. Like others mention though..I've seen reasonable pressure not running and poor pressure running, especially at wot.

I replaced with a TRE pump and have been thrilled with the performance. Look for higher flow as well as higher pressure.

i also tested it not running that was at 28

You need to find out if the fp canaster is the same on yours as it is on the later models. The SII might have a higher flow fp than the SI but the canaster should be the same. You can probably get part numbers from the dealership. If it is the Racetronix pump will work.

You might want to replace the in-tank fuel pump. If you have a little time on your hands get the rebuild kit from an ACDelco pars dealer - the replacements are pricey (I've seen $400) but the metal jacket pump itself is less than 1/4 that, around $40 or $60 IIRC.

what should i order

the '98-00 L67 I think BUT DON'T take my word for it, see what ewolfe (or who was that sent you to zzperformance) says.

BUMP any one know what year i should order or if it i need to know ASAP

Call Paul @ prg performance. He'll hook you up. There is some slight modification to be done which he can walk you through. He can probably save you some cash too...

Eric, what is Paul's contact info?

yea i just need to get back and forth to work i dont like buying gas for the titan

His site was down last night.. probably cause he found out I told another Riv owner about him. He is die hard GTP but somehow I get him to work on my car. He swears each time he sees my car he will not touch another Riv again. He's learning tho... 317-537-4004
