Backfiring equals pre-ignition caused by an engine that is out of timing. Shop work!.. backfiring can cause major problem with the valves.

In order to troubleshoot this, you must start with a clean engine wipe down.


The major offender parts are


air intake gasket on the manifold

air tube after the mass air flow sensor

rubber seal under idle air control IAC motor

===

Warm up the engine for 15-20 minutes (LEAVE THE engine at idle) then spray a little Barmen carburetor clear on the potential air leak location (ONE AT A TIME) and listen for a surge in rpm.

If the engine speed go higher that's mean the carburetor cleaner (ADDITIONAL FUEL) got into your engine and that's the gasket you need to change.

There may be multiple leaky spots so take your time and check all rubber gaskets,sensor and hose that are lead into the intake manifold.

When you finish fill up with one tank of Chervon to clean out the injectors.


Try to get a toque wrench and tighten ever bolt on the valve cover back to specification. If you can not get hold of one then just give each bolt a gentle 1/6 turn.



Please post more information after your inspection.

If you hear a click under the hood from the starter the starter solenoid but starter is defective and you should rebuild it. If that is not the case I would replace the ignition starter switch, this is the electrical switch the key cylinder actuates to turn on the electrical system and engage the starter.

dear friend-it is very difficult to explain myself in a text. I would say ignore the fault codes at hand for a while untill we have a definate fault. I would like you to make sure that the battery is fully charged, when you carry out the next exercise. I want you to try and start it with quick start, but please do not crank to long, gentle squirts will do it. If no joy, then we must go live chat- I am sure it will work, but please come back to me
