Check ECM (engine computer) located under glove box. Injector circuit output probably dead. Replace ECM. Go to Searchparts.com for best price.

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.

I have a 2003 Oldsmobile Alero 3.4L that wont start. I have done fuel pressure test 50-55 psi and plugs have good spark. However when done light test on injectors there is no response so there is no pulse....


Is the security light staying on ?
Usually the engine will not crank and you have no power to the fuel pump if the security system is disabling the car.
No injector pulse but spark would point to the computer since both use input from the crank and cam sensors.

Still need an answer to why my 98 explorer wont start ,started just fine 3 minutes prior spins but no start get spark compression fuel but no start if i wait a day or two it almost starts but dies qi


Check if the injectors are pulsing when cranking the engine over. Listen for the tick, or feel for the pulse with your fingertips, or buy a cheap "noid light"-an injector circuit tester- one that fits your injector harness connectors-plug it into an injector connector and crank the car. If circuit is working the noid light will be flashing.
Some anti-theft systems immobilize the injector circuit when they are activated. So you have spark, compression, and fuel to the engine, check the injector circuit.

Wont start\good fuel pressure\good spark


Then the fuel injectors are not pulsing,replace the crankshaft sensor,it controls the spark,but also the pulse for the injectors.

Fords have inertia fuel cut off switch. You need to check that first. If you dont have fuel. If you have fuel and no spark you need to check for inj pulse to injector. Make sure no fuses are blown. If no spark and no injector pulse then replace cranksensor.

Wont start


Make sure that you're getting spark. A very common thing on these engines are coils going bad. If you can verify spark, check to make sure you have an injector pulse. As you rotate the engine, look inside of the throttle body and make sure that you see fuel pulsing into the engine. You can still have good pressure but you don't have an injector pulse, the fuel still cant get into the engine. You can use a test light as well to test for an injector pulse. One wire going to the injector will have constant power and the other will blink when the engie is rolled over. Does it start if you spray starting fluid into the throttle body? If it does, it's a fuel delivery problem. Again be sure you have spark from coil to distributor and plugs. You can remove the ignition module and take it to NAPA and they have a module tester. Have them test the module several times not just once. This will eliminate the possibilites of an intermitted problem. Let me know how it does. tiqautoperformance@live.com
