2002 Olds silhoutte wont start

02 olds silhoutte at first it would not start have gas and spark then for no reason it starts but idles at 2k now gas and temp gauge radiator fans ac clutch dont work thanks jp.

Re: 95 olds sillhoeutte 3800 cranks, starts for 1.5 seconds and dies

the fuel pressure should go up a little bit when you disconnect the vacuum line to the regulator but that is while the engine is running. If you have a rubber return line you could pinch off the return hose and get a deadhead fuel pressure. that would tell you is the regulator is reducing the fuel pumps pressure from the tank of if the pump is maxed out. But like I said before 38 psi is below spec but it should be enough to make the engine stay running. Should be anyways.

while 95 might not be obd2 it should still have the obd1 connector. OBD1 should have the 12 pin connector and the OBD2 should have the 16 pin connector. this is the obd1 connector.

95 aurora vacuum lines from Crusoe control 3 of them, just where the lines run to all of them throttle body and is there a transmission one


Like you said, there are two cables to the throttle body plate. One comes from the pedal the other one is for the cruise control. Try unplugging the cruise module and see if that stops the unintended acceleration

Door Lock & Radio Issue (Alero)

I just picked up this 2004 Alero with 51K miles. The car is literally like new except for these couple issues. I'm not sure if they are related or not. Everything is stock original. Here's the scenarios:


Start engine, put in drive

Doors automatically lock

Stop car, put in park, kill engine

Doors will NOT unlock automatically


Turn key to on position or start engine

Radio plays and works perfectly

With radio "on", turn key to off position, remove key, open door

Radio still plays,

Get out of car and lock doors with remote, radio still is on.

unlock doors with remote, open and shut door(s), re-lock doors with remote,

radio then turns off.

Can someone please tell me what to check to solve these two issues? This is my sons first car and I want to make sure these issues are fixed before I turn it over to him.

'99 Olds 88 lowbeams

I have a 1999 Oldsmobile 88, and the low beams aren't working. hi-beams and tail lights work. One low-beam went out, and when they went to change the bulbs, the second one also went out.

2002 olds Silhouette

My 2002 olds Silhouette was running great but I let my nephew drive it to Idaho from South Carolina, now before he drove it I had noticed that when I tried to crank it,it wouldn't turn over but I would try to crank it again and it cranked right up. The van ran perfect, no knocks in the engine or problems with the transmission.It ran perfect going to Idaho although hesitated to crank once on the trip. As soon as he made it to Idaho to his apartment

He turned it off and when he tried to crank it it would start at all, he tried jumping it off but no luck so due to money constraints the van sit a little under a month and he finally towed it to the mechanic and they replaced the starter so now it will crank butt it won't stay cranked so now they are trying to figure out what's wrong. If anyone has any suggestions I would appreciate it.

1990 88 Royale wont start when hot

I have a 90' Olds 88 (3800 Series 1) with 60,000 miles. When the car is driven for 30-40 minutes and you turn it off like you would do to stop and get gas the car will not restart. I have to wait 2 hours for it to fully cool down before it will start up again.

I have replaced the fuel pump, sending unit, ICM, EGR, MAF, Idle controler, fuel regulator, alternator and crank position sensor. What would cause this to happen? It makes no sense to me so any help with this would be greatly appreciated.

1998 Oldsmobile 88 stahled out and now won't turn over

I was driving my 98 88 Oldsmobile that when driving, sputters alot. I stopped yesterday and put $10 gas in the car. When I left the gas station, I got to a red light about 500 ft. away. As I waited for the light to change green, the car stalled out and now won't turn over? The more I try to start it, the worse it seems to get. It's to the point now that it doesn't even want to try to turn over, it now is starting to just make a clicking sound. Don't know what the problem could be?
