Hi i been using these forums for quite a while now and have searched about every combination i can think of for an anwser to this.
I bought a 99 GS with the 420A engine about two years ago and lately have been doing some upgrading and modding to it. After a little research I am starting to belive i have a 95 engine dropped in my 99 car. The fuel rail on my engine looks to be the 95 with the fpr on the rail and I also have a fpr back by the filter. The return is blocked off on the rail and i have been looking to see if it hooks up anywhere. After doing some searching i know now the car was originally on the returnless system. My qestion is can i just unpug the vacum on the fpr on the rail and use the one by the filter or is there an issue with running two at the same time?

yup, and if there's a FPR in the rear near the tank, then the rail FPR is not being used

Thanks fellas i appreciate it. I was pretty sure that was the case. both are hooked up up the moment but I am just going to cap off the one on the rail then. This thing has been something else while working on it.Im almost positive someone put a 95 engine in my 99.

Yeah, I knew there wasnt really any major differences other then the fuel/evap stuff and some sensors and what not. It just threw me off when I saw the plugged return and coudn't find where it went. I recently registered on this website and so far have found alot of useful stuff while working on my car lately. I have been browsing the forums for along time now unregistered though. I love 2gnt for all the infomation I have found. I figure if im going to do a build on this car i might as well get the advice from others who have done it as well. Thanks again for the quick replies.

Do yourself a favor and hop into the wiki section on here. Spend some time getting acclimated to it. You will find yourself using it more and more as you get more familiar with what's in it.

I have a 99 and someone did the same thing, a sure way to tell is the main bearings. A 95 has the tangs one the same side when lines up and 96-99 are on opposites. Check before a rebuild. It will save a lot of time and frustration. TRUST ME!

I'm guessing you skimmed and didn't read that part?

No, I read that part. I just didn't see how that connected up to the problem the OP had. He needed to identify it with the engine already in and running. Seems like you wanted him to rebuild it so he could identify...... Of coursssssse, if we really want to get technicalllllll, we could say that he may NOT actually have a 95 engine in there. He may just have the rail out of a 95 and the engine could be from a 96-99. Or the engine could even have been pulled out of a 95 but not have been a 95 engine. It could have been pulled from another car (say a 98) and put into the donor 95 car. Then it could have been pulled from that car and put into his car Oh the pastabilities......

How about counting the pin connector to the ECU. Compare it to car with 96 to 99 420a engine. Would this be another way of detereming what engine is the car. Could also help those roaming in the junkyard looking for a long block? If so, OP unplug your ecu an take a picture of the pin connector and post it up.

Why would he have anything other than a 99 ecu in it, Dale?

He has a 99. With a 99 wiring harness. And a 99 ecu.
