The motor is actually in a truck not a car but since it is similiar i was hoping some of you guys might be able to help.

I was driving my truck one night and it was running strong as can be. Then the next morning I went to start it and all it would do was crank over. I pulled the spark plugs and they were all firing properly and had good gaps so then I pulled the fuel line after the filter and it had good pressure.

I am at a loss because my truck is getting fuel and spark, I however didnt pull an injector to see if they were squirting good or not. I am hoping it is not something with the injectors because I had to replace them on my 240 and it got very expensive in a hurry.

So if anyone has a good idea or any idea at all it would be very helpful.

 

starter?

 

no it cranks over fine

 

kinda simple but are you sure that you have oil.........i mean for real you have to check really stupid shyt first and then check you fuses..........

 

i am a follower of this theory. check stupid easy or cheap stuff before you go blow money on stuff it doesn't need at the moment. i however did check fuses and do not know why it wouldn't start without oil because it has spark and fuel.

I went outside to go to work this morning and it started, but ran rough, almost like a misfire. About 2 miles into my journey it started dying when I put it in neutral and had to keep my foot on the gas when at a stop. Che check engine was also on.

I am going to check all vacum and all connections today.

 

Ok get this I took it to a friend of the family's shop and had it ran on a diagnotstic thingy and it showed up as a intake tempature sensor so I found that and it was unplugged. I plugged it in but then it wouldn't start again

Then I pulled the MAF and it was dirty so I cleaned it and it ran better after I put it in. The owner of the shop said it might just be bad because they said it was acting like the motor was confused and just giving itself two much fuel (it was pouring out black smoke). They also thought it might be the collant sensor telling the truck that it was colder than it actually was causing it to get more fuel and run rich that way. Anyway we pretty much narrowed it down to to much fuel whatever is causing it to run bad is making the computer give it too much fuel.

if anybody has an extra MAF or coolant sensor for cheap let me know and hopefully i will have an answer tomorrow.

 

CHECK THE MASS AIRFLOW SENSOR!!! I had the same problem with the dying in nuetral (idle). It was my Mass Airflow Sensor.

 

You are on to something and I do have a spare if you are interested. zero.counter@gbronline.com

Not to hijack your thread mwdrifter, but Baloo, youre an idiot. Plain and simple. If it didnt have oil, the rods would knock and you'd throw one. DUH. it doesnt take long for that to happen either. You would definately know the oil was empty, especially when the oil light comes on. Its there for a reason ya know.

Im done flaming for now, but yeah mw, i would say the MAF is bad, if nothing else, run some seafoam through the motor, does wonders!
