I have a 2004 Isuzu Rodeo V6 - 3.5L vin Y 3494cc type 6VE1 - MFI GAS DOHC.
Car died right after 100000 warranty expired! 100029! Timing belt replaced, Denso Spark Plugs Replaced, Crankshaft Position Sensor replaced, still nothing.
Car turns on, but won't start all the way. Will not turn over. Looks like a delay in the spark. Please help!
NaTasha
Oh and the fuel pump was replaced at 68000 miles due to the recalled pump.

Hello!

 

We will have to pinpoint what the engine is missing.


Spark


Fuel


Compression

 

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the car to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should! Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

 

A simpler test would be to see if it runs on starting fluid. If it does, then you know you have spark and compression and you simply have a fuel delivery problem

Well, we already tried the starter fluid test yesterday. It's almost like the engine is not getting enough spark. I am about to go tell my husband to come read your answer now, so I know how to accept. I am new to this website and we can't find a repair book for the 2004 Rodeo.

You can accept my answer now and we can still continue our conversation after you accept one of my answers.
