Will not start

Hey ANDREW LLOYD,

Just to be sure I have attached the process for checking for spark below.

If you have verified that you have no spark there are few things to try, starting with checking fuses.

I will run you through fuses and points to check for battery voltage below.
This system has a separate ignition control module as well as the ignition coil and the PCM.

Regards, Joe

Hey Andrew Lloyd,

I have attached the engine controls wiring diagram below.

Things to check first would be that fuse 4 (30A) in the under hood fuse box is in tact and has 12V at both sides.

I would also check all other fuses in the under hood fuse board as a precaution while you're there.

Guide to check fuse below:

Also check battery connections and engine ground wires to ensure nothing is loose.

If this is okay the next thing i would do is to remove the distributor cap and check the condition of the cap and rotor contacts. Make sure the rotor is seated correctly and the cap is fitted correctly.

Check the connections of all of the plug wires and the lead from the ignition control module to the center of the distributor.

Check connections on the Ignition control module (ICM) and Power train control module (PCM).

The ICM is mounted to the to the radiator support, left front of engine compartment.
PCM left rear corner of engine compartment.

If all connections appear okay and you have power at the fuse you will need to check for voltage at the ignition coil and at the ICM.

Do you have access to a multi-meter or test light?

Regards, Joe

Hot or Cold engine

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

Hello,

It sounds like you may have lost the timing belt. Can you check the compression for me, here is a guide that will show you how.

How was the compression? Im wondering if you have a broken timing chain or belt that why I ask.

Scan for codes and check fuel pressure with a gauge first auto parts rent it. see link

If not-Lets do below for a start to determine if its fuel or spark related issue and get back asap.
