Very important that if you are not savvy of working on your Vette ...you would be better off - taking your car to a dealership for repairs on your trouble codes. However if you feel that you want to, First locate your car's alcl this component is located just below the instrument panel and to the left of the center console. Remove the plastic cover the first two slots to your right are the A & B slots.
The A slot is the diagnostic slot and the B slot is the ground slot. Insert the computer key into these slots if you do not have a computer key, a paper clip or wire jumper clip will do, (with the engine off) this is very important...now only put the ignition key to on ( not start !!!) the check engine light will display a code 12 which is one flash followed by two flashes. This code will be flashed three times ..followed by the trouble code stored in your car's computer.

What ever the code is it will be flashed three times. Have a paper and pencil ready and write down the code.

Code #12: Normal No Codes. 
Code #13: Open Oxygen Sensor Circuit. 
Code #14: Coolant Sensor Circuit Low.
Code #15: Coolant Sensor Circuit High. 
Code #21: Throttle Position Sensor High. 
Code #22: Throttle Position Sensor Low. 
Code #23: Manifold Air Temperature Circuit High.
Code #24: Vehicle Speed Sensor. 
Code #25: Manifold Air Temperature Circuit Low. 
Code #32: EGR System Failure. 
Code #33: Mass Air Flow Sensor High.
Code #34: Mass Air Flow Sensor Low. 
Code #36: Mas Air Flow Sensor Burn-Off Function Fault. 
Code #41: Cylinder Select Error. 
Code #42: Electronic Spark Timing.
Code #43: Electronic Spark Control. 
Code #44: Lean Exhaust indication. 
Code #45: Rich Exhaust Indication. 
Code #46: Vehicle Anti Theft Fault. 
Code #51: Faulty Mem-Cal. 
Code #52: Fuel Calpak Missing.
Code #52(1990-91 Corvette Only): Engine Oil Temperature Sensor Low. 
Code #53: System Over Voltage. 
Code #54: Fuel Pump Circuit Low Voltage. 
Code #55: Defective ECM. 
Code #62: Engine Oil Temperature Sensor Circuit High.

Please remember that if you have the computer key installed in the alcl and you start the engine (you will ruin the engine's computer) only put the ignition to on (not to start).

If you should get a check engine soon display.. you can use the above procedure and codes to buy the right part or at the very least to keep from getting taken for a ride and be made to pay hight prices for some inexpensive module that you could have installed yourself.

If your engine displays a trouble code ... your engine will go into limp mode ..it will still run but very poorly. You might be able to reset the computer if it will not start (just to get home) by disconnecting both battery cables and re-installing them ...this is not recommended ..but if you are stranded it might help unitl you get your car home or to a repair shop..good luck.

Good luck and hope this helps.

Before you go any further open the trunk and check the fuel pump roll over valve switch, mounted on the left side inside the trunk, push the switch down and try the vehicle.

SOURCE: Volvo 240 2.3L FI the engine has spark, no injector pluse.

Pull the return fuel line off the back of the fuel pressure regulator and plugit.
attach another hose and clamp it to the back of thefp regulator place the othe end in a container.
pull the coil wire and have someone crank the engine or use a remote starter switch.there should be a steady stream of fuel into the container. If not check your intank pump and main body pumps for electrical connections.
If there is a steady stream from the fuel rail and still no gas at the plugs.
Find another fuel injector for a volvo,unplug the # 1 injector electrical connnection and plug in the extra one placing it in a container and crank the engine over. There s/b an even spray of fuel from injector.
If not check for 12 volts at the injector connectrion. If no volts,check backwards to the ballast resistor which controls the injectors and then to the radio suppression relay etc.

N0 p0wer to fuel pump


I have to ask. How long since a tune-up? Are there any applicable trouble codes?
With engine cranking, if no spark at the spark plugs and no fuel injector pulse along with no fuel pump action, have to check rpm signal.
If you have spark and fuel injector pulse but, no fuel pump action, then we check the fuel pump circuit. Did you check applicable fuse, not only check the fuse, check the fuse circuit for voltage. At the fuel pump connector, gray wire is voltage for fuel pump motor and black wire is ground.

Runs good, after 30 mins stalls no injector pulse and hard to start.after 10-15 mins starts again, spark OK. changed fuel pump,distributor. Same


run the fault codes and check for problem ECM
There is an electronic component failure in the injector circuit that when over heats , shuts that injector circuit down
try replacing the ECM with a known good unit

My 2000 Pontiac grand prix stop running the other day. It turns over just fine but it won't fire up could it be anything other than the fuel pump. ( I really don't want to change that)


its pretty simple to check for fuel pressure. If there is no fuel pressure than the next step is to check for power and ground at the pump. if those check out then a new fuel pump should fix the problem.

your engine needs 3 things to run. fuel, spark, and compression. if you have fuel pressure than check for spark. if there is no spark than there could an issue with a crank or cam sensor. If the crank sensor is bad than typically there will be no injector pulse as well. after cranking it over a couple times pull a plug and see if it is wet. if it is you know the crank sensor is working and the fuel pump is working and you have a spark issue. If it is dry than there is a fuel delivery issue (fuel pump/injector/injector pulse/etc.)

there are many things you can check very easily to help narrow down the possibilities.

My 2001 Saturn, will start but not stay running. We have checked the fuel pump and all fluids. Did a compression check this morning, fuel injectors are not injecting fuel into fuel rail. Why is engine...


You said, 'fuel injectors are not injecting fuel into fuel rail' but it's my understanding that the fuel rail gasoline is supplied by the pump, and the fuel injectors just pulse to allow fuel to get to the cylinders. I would check out the fuel delivery problem further. Check for pressure in the fuel rail that is within specs.

If not, then the pump or fuel pressure regulator may be the problem. Check the fuse for the fuel pump. If good, then the pump may be bad in the tank.

Good luck on this.

Engine will Turnover but it will not fire up


To check injector pulse, you need 2 people. One is to crank the engine. The other is to watch the voltmeter connecting to the plug delivering the electrical signal to an injector. If during a period of cranking, there is no voltage displayed that means there is no injector pulse. Here is an image of connector port going into the injector to open its valve as needed.d63fc52.jpg

Crank no start: has no spark and only has injector pulse on cyl # 1. if you spray starting fluid directly into throttle body car starts and stays running and has spark and inj. pulse. once you turn the car...


Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.
