Well David , there are many variables as to why a combustion
engine won't start . And the information you have given is vague and with the parts you listed, you seem as though it's an ignition problem ...... and was curious as to why ? Here's the juice. ....
I have been turning wrenches my whole life,I still do and at 51 yrs
i have finally concluded that I will be turning them for a long time in the future...... I don't know why so many think that ifthe engine
dont start and run its always in the ignition . .. This does hold true many times but let's briefly get back to the basics .
it doesn't matter if you know the make, or model .....Or the cu inch. If it's a Briggs and Stratton 10 hp to a 400 small block with
double camelhump heads and a 750 Holley dual line two time pumper .......turning mid 4s at the strip ?. A 4 stroke. Combustion engine is

Put an injector noid light at the injector plug terminals to see if your getting a signal from the PCM(computer).If not try to find a computer from the same vehicle that works and swap it into yours to check.A PCM swap will take about 15minutes.

Sounds like a vacuam leak, best thing to use is cold start spray, by spraying the vacuam lines with this you will notice a change in the idle wherever the leak is at.

SOURCE: Toyota Camry 96. Won't start the engine turns over

Ignition timing could be off, the plug wires and firing order may be scrambled, there could be a large air leak into the intake manifold, the EGR could be stuck open, the fuel pressure is too high and flooding the engine through the cold start injector, the MAP or MAF sensor is faulty, very dirty fuel injectors, idle air control valve defective, the engine coolant temp sensor is faulty (stuck at full hot).

Car cranks over, but won't start. What could be wrong with it?


Crank sensor, ignition module, coil/s, fuel pump.

Car wont start not the battery


Starter switch, starter relay, or starter motor. If it cranks, but don't start, check fuel pressure. If pressure is not good, then replace fuel filter, fuel pump relay, and/or fuel pump (in that order) If fuel pressure is ok, then its ignition. check and/or replace coil or igniton module.

My car wont start


a) Do you have crank no start? (see entire write up)
b)No crank no start ,No dash lights?, ( battery, battery cables, ignition switch,,starter relay)

If you have symptom A then the affected items are , ignition switch, battery, battery cables, starter, starter relay ,coil, coil pack, ignition module ,Distributor cap ,rotor, (if applicable) spark plugs and wires.
The best thing to do is to first make sure your timing belt didn't break. As long as the engine cranks you can do this. Give the battery a 3 min charge . Then have a helper crank the vehicle while you observe the rotation of all the pulley's and belts. They must rotate together. If the vehicle has a distributor remove the cap, ground the coil wire and remove fuel pump relay ( to disconnect the pump for testing)and watch the rotor as the engine is cranked. it should spin. If this is a-ok your worse nightmare is over.
Now we have eliminated the timing belt as being a cause. We now have to charged the battery again for three min and load test it( this is best done by a repair shop a load tester is expensive .If the battery if more than 5yrs old you may want to replace it.
If battery does not pass load test replace it.
Whatever you decide the rest of the items can NOT be checked out without a fully charged battery.
Check ignition switch and starter relay for B+ going to them and leaving them. Check starter circuit. Make sure B+ is making it to starter ( use a digital voltmeter). If B+ (12 volts) is making it to the starter and it doesn't crank then the starter is defective. Verify this by removing the starter and have it bench tested.
If starter cranks now your into coil testing . First thing reconnect the distributor.
Pull a spark plug, hook it up to a spark tester and ground it, now crank the engine if you get spark coil is ok and in all likelihood so is module.
If you don't get spark test for spark at the coil wire.
If you get spark here and don't get it at the spark plug wire problem is at distributor cap , rotor or spark plug wire. If plugs look bad use a fresh plug to do testing and naturally replace them.
If all of the above are a-ok.
Next is fuel checks. Reinstall fuel pump relay
Easiest fuel check is to put key into ignition cylinder and turn to on position. Lister for pump to buzz or hum. if it doesn't then check fuel pump relay for B+ going to it and leaving it and going to the pump. If B+ making it to pump and it doesn't turn on the pump is your problem. If B+ not making it to pump either the relay or the ignition switch is defective.
Naturally if the pump is defective have a repair shop do the repair . Its dangerous and a real pain.
Good Luck
Now the cutting out after running fora whilrcoild have caused by the coil, ignition module, fuel pump.
We kinda have to get the car to start first to be conclusiveas to why it cuts out.

2000 Toyota Camry did not start on first try - yellow symbol


Hard to say what it is without testing so I 'm gonna give you a list of things you or a repair shop can check out:
SYMPTOM :NO CRANK
Battery,battery cables,ignition switch, neutral safety switch, starter relay, starter.
SYMPTOM: CRANK NO START
MAKE SURE TIMING BELT DIDN'T BREAK OR SKIP A TOOTH,STARTER current draw test , coil, coil pack, ignition module( only if no spark at the plug wires) fuel pump relay, fuel pump, injector module and drives, fuel pressure regulator.

This year Camry is a good year. Very little problems except annoying EVAP system. TIMING BELT SHOULD BE DONE EVERY 60K . ALONG WITH CAM, CRANK, OIL PUMP SEALS AND WATER PUMP.
I recommend taking your car to Sears Auto Center
they are pretty good with this kind of work.

Whatever you decide the rest of the items can NOT be checked out without a fully charged battery.
Check ignition switch and starter relay for B+ going to them and leaving them. Check starter circuit.Do not forget neutral safety switch its on your brake pedal and once depressed it closes the circuit to the relay so B+ can travel to it . Make sure B+ is making it to starter ( use a digital voltmeter). If B+ (12 volts) is making it to the starter and it doesn't crank then the starter is defective. Do a starter current draw test to verify this or remove the starter and have it bench tested.
If starter cranks now your into coil testing .
Pull a spark plug hook it up to a spark tester and ground it, now crank the engine if you get spark coil is ok and in all likelihood so is module.
If you don't get spark test for spark at the coil wire.
If you get spark here and don't get it at the spark plug wire problem is at distributor cap , rotor or spark plug wire. IN YOUR CASE YOU HAVE NEW PLUGS AND WIRES SO IT WILL BE EASIER TO CHECK FOR SPARK.If all of the above are a-ok.
Next is fuel checks.
Easiest fuel check is to put key into ignition cylinder and turn to on position. Lister for pump to buzz or hum. if it doesn't then check fuel pump relay for B+ going to it and leaving it and going to the pump. If B+ making it to pump and it doesn't turn on the pump is your problem. If B+ not making it to pump either the relay or the ignition switch is defective.
Naturally if the pump is defective have a repair shop do the repair .THERE ARE FUEL PRESSURE AND VOLUME TESTS DONE TO VERIFY IF PUMP IS DEFECTIVE OR NOT. IF WITH THE TESTING PROCEDURES I'VE GIVEN YOUYOU CAN NOT DETERMINE WHETHER THE PUMP IS DEFECTIVE HAVE A REPAIR SHOP DO FURTHER TESTING ON THE PUMP. THESE TESTS ARE A LITTLE DANGEROUS and a real pain.
Good Luck

Car sat for two years there is no spark and i can't hear the fuel pump working what other problems could i have ( installed a new ignition coil)


So you have no crank no start correct?
Battery must be fully charged ( three day charge) or new.Make sure battery cables are clean and tight.
Use meter and make sure B+ making it to starter .
If B+ not at starter then check cable to starter and neutral safety switch and ignition switch.

This is for crank no start

B+ goes from battery to Ignition switch to coil to switching device( ignition module) to plug.
use a volt meter and find out where B+ stops.
