I recently posted about some problems about my Explorer. Here is the latest trouble update. I had it towed to an electrical expert. He says the missing I was experiencing was because gasoline is being dumped into the engine like crazy and he doesn't know why. We have already replaced the EGR valve and put in another Mass Airflow sensor. Other things have been checked; so far it is all inconclusive. Cables check OK. Nothing is really sticking out as a cause. HELP! Anybody experince this problem?

its a 1998 4l v6 sohc all the fuel pressure is fine well the fuel pressure gauge says its fine its getting far to much fuel and fails to start due to the plugs getting soaked in fuel if u trip fuel switch it nearly starts but wont due to lack of fuel in the rail if you flick the switch on when it sounds like its about fire then it nearly goes but then soakes plugs due to the amount of fuel going in could it be the ecu ???? or can you get a faulty fuel pressure regulator???any help would be very much great ful

You need to check the exhaust for a restriction An easy way to check it is to get a small vacuum gauge and hook it to the DPFE hose and try to start the engine and watch the gauge if it pegs your exhaust is plugged. or you could just un bolt the exausht from the manifolds and try to start it. But before you do that remove your plugs clean them. and crank the engine over to get all excees fuel from the cylinders. then put ypur plugs back in and I'll bet it starts. hope this helps

Sounds like an ECT or IAT telling the PCM the wrong readings causing the flood.

OK. Here's what they found. There was a blown LOWER intake gasket(there is an upper and a lower gasket). With this it would flood cold or warm. After it was replaced then it would do it again when warmed up. This time they found a problem in the wiring harness under the air filter on the lines that fed to the ECT (Engine Coolant Temperature sensor)& the IAT (Intake Air Temperature sensor). They also replaced the sensors while they were at it.
We now have a problem with either the fuel pump or the harness feeding it. This thing has been a lot of trouble so far.
