Hey Andrea==Make sure the fuel pump has preasure. If it doesn't have spark check the ignition module GoodluckJoe Answer Good question! I have an 87 doing the same thing. Seems to happen more when the vehicle is up to operating temp. Mine is TBI, and when this happens, neither of the two injectors fire. I have replaced nearly everything under the sun, but have yet to find the problem. To give you an idea, I have replaced the fuel pump, both injectors, fuel regulator, fuel filter, dist. cap & rotor, plugs, wires, all vaccum hoses, egr, o2, tps, egr sel., ignition pickup, coil, iac valve, the pcm, and the distributor... there are other items I cannot recall right off the top, but I still face the problem. My frustration is out the roof. I am looking into a bad ground, possible bad prom or calpak, but I am grasping for straws now.

Most likely culprit is the fuel pump. Any mechanic can check the fuel pressure in under 10 minutes and shouldn't charge more than 20 bucks to check it for you. You can also buy a fuel pressure gauge from any auto parts store and check it yourself. Simply google fuel pressure check for your vehicle and you should get plenty of guides showing you how to check this.

A sticky brake caliper could do that.

There are a few things that could cause an 87 Chevy Astro to idle high when it is started and warmed up. It could be a bad fuse, a leak in the vacuum, or an issue with the throttle.

There could be a few reasons why a 2000 Chevy Impala shuts off while driving. There could be a problem with the fuel pump, a bad spark plug, or even a loose battery cable.
