HI;
Run and No Run Restart!“Service Engine Soon”Did you check your cars computer?
Did you put your cars ECM into it’s diagnostic mode and check for any trouble codes that maybe stored in your cars ECM / code 14,15,21,44 etc.
Do the following Checks:- Throttle Position Sensor (TPS) for sticking or binding or any high TPS
voltage with the throttle closed it should read less than {.700 volts}
- Coolant Temperature Sensor (CTS) for any abnormal voltage
{At normal Engine operating temperature [85deg.C to 95deg.C]
the voltage at the ECM Coolant Sensor Signal circuit will measure
about 1.5 to 2.0 volts at the ECM] also to check the resistance
values of the (CTS).
The Approximate (CTS) Resistance Values are as follows:
210deg.F = 185 Ohm’s
160deg.F = 450 Ohm’s
100deg.F = 1,800 Ohm’s
70deg.F = 3,400 Ohm’s
40deg.F = 7,500 Ohm’s
- Exhaust Gas Regulator (EGR) for valve seating properly.
- Loose Ignition coil ground / and bare or shorted wires.
- Ignition Pickup Coil resistance and connections.
- Distributor for proper output with a {ST-125} Tester
- For faulty In-tank Fuel Pump Check Valve (The check valve should not allow the fuel too drain back into the tank.)
Hope This Helps

PS. //
Also Please Note: A good rule thumb is; that when you deal with a car with a on board computer you should always try too check your cars ECM and wiring to see if it’s good to go first, before you make any repairs otherwise you can be spending a lot money for replacement parts before you find the problem!
