Ok i got the car started after a starter problem. Turns out i didnt need a new starter . I just added more grounds and that did the trick. Car fires up right away now. My question is what is a good oil pressure? I took sender off and put guage on it and fired it up and with a alittle throttle im getting like 60 psi and when i let off and its drops down. And i when i unscrew the guage a little oil flows out sender hole. Im sure that shows pressured then and Im thinking everything is good and im gerting closer now to finish. Tomorrow i plan on cutting and welding up the exhaust system. And where can i find the v6 oil pressure sender to replace the stock 3800 one? The auto parts store says its dealer only part? Anyone has the aftermarket part number or info? Thanks

I'm doing a 3800SC swap and from what I've read it says to use a 1988 Fiero V6 sending unit. I guess the 88 has 3 prong as opposed to the 2 prong. I'm 99% sure it said to use the 88 V6 sending unit. I'm jealous, I'm not even started with my build. I'm still collecting parts. I lost my job due to a back injury so I have to save here and there. Good luck with your swap.

Yea i know its from an 88 v6 But the auto parts stores dont stock it. They say its not even in the system to order. They say dealer only part. Kinda wierd to me.

Told you it wasnt the starter :-P

Mine has always run around 60 cold about 40psi warm. You dont need an 88 sender, Ive been running an 86 sender on mine since I first did the swap without a problem.

Any three/four prong oil pressure sensor, not switch, will work, the 88 is just smaller. Just check it has the signal wire. Some of them look like sensors but the pressure signal pin is blank

^^^^^ First thing I told you in your thread was you did not have sufficient grounds

Yea yea i know lol. You know i looked and checked all the cables before i figured i was good i didnt see anything wrong. Plus the car did start coulpe times with that set up. So i didnt understand how it could just stop working out of tge blue. But after digging in my pile of parts and wires i found two already made ground cables so i figured what the heck let me throw some more on. Cant hurt. And bam it worked. I was kinda shocked . So was my family they came outside in shock they heard nothing but cussing and disapointment and then hear the exhaust less car wake the dead start . Lol

Found these part numbers when doing my research. Not sure if they are correct, but came from Pennock forum.: Oil Sender AC Delco D1808A. Pigtail ( if needed) PT121, 12085499, or PICO 5609PT. Summit has the pigtail ( also on Ebay)

Sender's available on Ebay.

thanks for the info.... ok heres what I got today.. my oil pressure is fine. Ichecked all fuilds iv full and good.. and when I start it other than being loud because of no exhaust yet. that's a given.. when I try to fire it up it wont just start I have to give it some gas and play with the throttle while someone else cranks it . and then I can keep it going with my hand its having trouble idleing by itself its choppy and when it does idle on its own its up and down revs abit then wants to stall then I use my hand and keep it going and then I let off and it stalls out.... sooo I put my code reading it to see if im getting any codes. and yes I am.. I have two of them... 403 and 405 both are egr.. well that's kinda funny because I don't have a egr system no more.. I removed it all and have two block off plates.. so im thinking that these codes have something to do with car running like crap or lack of running. lol and im pretty sure I said I was going to do egr delete when the computer and harness was being built. any ideas folks? if not not one thing its something else stopping me from driving this thing everyday its something... lol

look at what I found on google.... with these codes... The code may be accompanied by misfire under acceleration, rough idle, or engine dying altogether. .................... that's what I got going on here... its doing all that.

My first thought is that if EGR was removed from the programming, you could not get an EGR code.

If you ask NAPA for a 88 sending unit they will hand you a 2 pin unit every time. you just gotta give them the Delco part # D1808A they should have them in stock .

yea that's what im thinking . I shouldn't be getting these codes and the harness has no plugs for them so its not like I can just put egr stuff back on and keep going.

guess im dead in the water till i figured out why im getting egr codes on a car that has no erg system left on it and harness built with no egr plugs on it.. im thinking this egr issue is whats causing my car poor idle and wanting to stall and now wont start. but i get these code while trying to crank it. i guess ill work on building the exhaust today.. for a car that i still cant drive yet again.. lol

Highly doubt EGR codes are the problem poor idle and stalling is usually a vacuum leak but until you have an exhaust on the engine to allow the O2 sensor to read properly you will not know for sure

all vac lines are hooked up no leaks there... and guess what still no running car.. go figure didn't expect it to. still have egr codes coming up even after I take them off and soon as I start trying to crank this pig they come right back. po403 and po405 and now the the great paper weight of a car wont even start.. just cranks and cranks sound like it wants to kinda.. oh but if I use starter fuild it runs just fine till the fuild is gone then shuts down... form what I read sounds like we can add that it might be the vehicle theft system doing that.. I hate this car.. with each day that gos by . its funny a car always wanted since a child and now I hate it. isn't that ironic.

Goodmorning . Well guess its an other day of trouble shooting for me yet again. I think i spend more time on this fiero than i do at my real job. One i make money at . And the other takes my money plus more. The fuero used to be called my mistress . That might be true if i enjoyed it. Iv renamed it to ex wife.

Make sure Icm has power the blue wire I believe . Icm maybe bad I'm having trouble with my car too if you have another switch it out. Check make sure crank sensor camshaft sensor and all sensors are working right. Could be the vats anti also it won't fire the injectors.
