Driving down the road the engine died. Towed back to house. Fuel pump primes and runs for 7-8 seconds and shuts off if not being cranked. I don't seem to have spark. There is a ignitor compounent on fire wall. This is before obd and the diagniosis module in engine compartment is confusing.. What should I look at, they want 185.00 for new ignition module but I need to know thats the problem for that price. Please help. I have a multi-meter, I need to know where to look. Checked fuses all ok. Please help.. Thankyou ted

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Yes you are right I just have to find the chiltons for this for specific location of components cause I am not finding coil or fuel plug. I have test equipment but this car may be to old and I am used to chevys, dodges and fords. Thankyou for your help... ted

If it's not a California model, the coil is inside the distributor. The fuel injectors are on a rail right on top of the motor.
To test fuel pressure, you may have to tap in at the fuel filter. You will need some adapters.
