Question about 1990 Oldsmobile Eighty Eight

1 Answer

I have a 1990 olds 88 royale 3.8 Just replaced the fuel pump, and both fuel filter. A week later coming to a stop the car dies. It's seems every time I approach a stop and get under 25 mph it dies. Sometimes it restarts in nutrual or park, but most of the time it won't because the battery is to low. After a couple of hours It starts. A friend used his code reader thing and it said:(TPS) low. I changed it. It still dies. Can't figure it out...help. Donald

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

hi hurdle
im dave

how do you know fuse is good?
sometimes just looking at it doen't prove that
you need to check it with a test light on both blades with either the brake pressed or the signal on. both sides of the fuse should light

On many vehicles the fuel pump is accessable from above the tank. For Toyotas it is under the rear seat, there is a plate that is removeable to repalce the pump.

It could be in the trunk for the olds.

You've got to do the obvious things, look at your spark plug wires, if you see what looks like chalky residue they are arcing replace them and your plugs. Check all vacume lines for leaks, and make sure your air filter is clean

89 regal won,t start but after 5 or 10 min. runs great


sounds like your fuel pump is going out. One thought might be that the fuel filter is causing enough resistance to over heat the pump. I would check the fule pressure to determine a free flow of fuel.
