20 Most Recent 1990 Chevrolet Corsica Questions & Answers

The fuel pump relay should be under the hood on the firewall, square with a 3 in it. Hope you can read it?

Hi. There isn't one answer for this issue. Do you have any test equipment? I would start with the vehicle's maintenance history and mileage. Last tune-up (W/fuel and air filter). Any recent repairs that were performed before this issue started. Take a look at fuel pressures at curbside idle and while under a load. Also look at the engine vacuum. Normal vacuum is 16 in/Hg and the needle on the gauge should be steady (Not Fluttering). Good Luck.

It will be the thicker of the two ac lines and probably on the passenger side near the center. If you need further help, reach me via phone at https://www.6ya.com/expert/chris_b82b45c59bcf133d

replace the air cleaner and spark plugs may be bad.This should help alot. Make sure tires are properly inflated, this will put a drag on car, and waste fuel. or try a different brand of spark plug recommended for your car. I have a 09 kia, I just put iridium plugs in it, and it runs much better and the mileage is good. these are the original plug type. there more expensive, but worth the price.

Start at the battery. Check for clean, tight connections. Any chance it is discharged? It needs to be at lest 12.6 volts on a voltmeter to be ready to start the car. Is there power from battery to the ignition switch? Turn key on. Do warning lights and gauges come on? And accessories work? Then there is power to the switch. If nothing, start checking fuses and fusible links that pass power from battery to the switch.An electrical circuit is a complete electrical path from a power source to an electrical load to ground, and back to the power source-the battery. The starting circuit is just such a circuit. From the battery to the key switch to a relay or switch (neutral safety switch) or two, to the starter, and then to ground-back to the battery. If the key turns power on, one could next see if power is getting to the starter solenoid, mounted on the starter. The small wire to the solenoid should have power to it when the key is held in crank position. Use a test light or voltmeter to check for power there. If has power, likely the starter or solenoid is bad. You then need to take it off and have it tested-a free service at most parts stores. If no power is getting to the solenoid, but the ignition switch has power, further testing of the start circuit will have to be done -the clutch switch (or neutral/park switch if automatic trans.), the starter relay, and whatever else is in your starting circuit.If car has an alarm system, make sure it is not activated, so the immobilizer function is not causing a no start.Good luck. Post back with results.

try checking computer system wiring, does your horn work

Was it running before you replaced the parts ?Does the engine crank ?What have you checked so far ?

intake manifold gasket may be bad,if the coils were bad you would get no spark and no fire i doubt its your plugs

MAINTAINANCE, this is an important word ! an never assume ! tune-up is another, so begin with tune-up, spark plugs, wires, cap / rotor, fuel filter, oil filter, fresh oil, transmission filter /fluid , very important, air filter must be changed also. don't go over 45-50mph until you do all of the above dude. put some drygas in your tank, red bottle, has fuel injector cleaner in it. now get to work !!!!!!!!!!!!!!!!!1

The fuel pump is inside the gas tank.It's not the easiest job,but not impossible for a do-it-yourselfer.

you usually have to bend the metal brake lines to fit if it's the rubber line it should be easy to follow how to install it you need to bend the metal lines away from any sharp edges
