Walbrol ordered and afpr on its way.... hopefully this will fix it. If not a few extra pieces towards boosting never hurt

It really seems odd that you had the issues occurring at a certain fuel level in the tank. The only time I have ever seen anything like that was when I worked on Ambulances. Ford diesels had a problem with algae growing in the tanks, when the fuel level started to get lower they would have power issues. Is it happening now regardless of how much gas is in the tank?

**friendsofdonr** · 1-2-13, 22:38

Yeah I have over a half tank now. Its not dependant on fuel levels now. Which prpbably means its getting worse.

Today it died on the way to work. It started missing a little and then would stutter above half throttle when trying to accelerate.

The thing that I have noticed is before it starts to try and die it idles around 1.5k for a bit a few red lights then doesnt want to hold a minimum idle around 750 tries to hold at 250 when I pump the gas it revs back ip but if I don't assist it will die. In traffic today I couldnt keep it going and it died. Then wouldn't start...

It cranks fine but wont fire.... I pumped three or for times then tried to crank and nothing so I held the gas pedal down and started to try and crank it... it started so I drove it to my parking spot near work.

I drove it home tonight really carefully and it only died once. After it died it held idle around 1.5k the whole way home. I live 10 miles from where I work. The problem doesnt occur until a mile or so of driving. Or operating temperature has been reached for a bit

Sure sounds like a fuel pump to me. But replace your fuel filter first.
Here's a test you can try: when tge car dies abd refuses to start, have a friend kick the fuel tank nice and hard while you crank it. If it fires, then you can guarantee that it's the fuel pump. The idea is to create a sudden pressure surge in the fuel system. Its not 100% of course, but it might save you some time

Thanks guys. I ordered a pump and regulator. So the car is on time out until I can get it died. Ill keep you updated. Ok shooting for install this weekend. Assuming my parts get here on time.

On a fuel injected car holding the pedal to the floor while cranking actually temporarily turns off the injectors so they don't do their initial fire sequence. When you crank all the injectors will fire at once. When you held the pedal to the floor you actually cleared the cylinders of excess fuel. Another thing, pumping the pedal in a fuel injected car doesn't do anything other than open and close the throttle plate when the car isn't running or cranking. I got the Alldata password today at work. I'm gonna check some things when I get home tonight and see if I can help out a little more.

That's interesting. Is this so that a fuel injected engine can be cleared should it ever flood?

Honestly I'm not sure what the exact reasoning for this is, but that is how I have always used it. Fuel injected cars don't flood very often unless there is a spark issue or fuel contamination issue. Toyota corolla and matrix had issues with long crank and no start issues. The no start would cause them to flood the cylinders and be nearly impossible to start. We get them dropped off at the dealership all the time and you have to hold the pedal to the floor to get them started. Then I get to do an ECU recalibration and paid for an hours labor for 20 minutes of sitting on my ass, lol. Warranty btw not customer pay.

**friendsofdonr** · 1-3-13, 23:31

So mr I got an alldata password.. any help? Lol.
On a seroous note: If holding the pedal down clears the injectors than would I want to look into clogged fuel lines or a fuel filter? I changed the filter before I drove to seatlle for a car show over the summer and theres less than 10k on it. Shouldnt have clogged. In that amount of time and it had a little miss in the idle nefore that but no shutter like I have now.

I started to do some checking. Holding the pedal doesn't "clear" the injectors, it turns them off. Do you have a timing light so you can check ignition timing? Also, if you can get it to crank and not start then pull a couple of spark plugs and see if they are fuel soaked that will also help to see what's going on.

**friendsofdonr** · 1-4-13, 8:55

no timing light. I had the timing set before and after I swapped the cam. If for some reason I hadnt set it right I could understand new problems but when it did it before I put in a new cam it shouldnt be that.

Next time it dies I should pull the plugs? I can try and let it run for a few minutes and see if it will die on me in my driveway.

natev8 · 1-4-13, 11:48

Im talking about ignition timing that you adjust with the distributor, not your valve timing. I would only pull the plugs on a crank no start, not if its been running.

**friendsofdonr** · 1-4-13, 11:59

I don't plan on driving it until I get the pump so I can take it to my friends place with a lift. That should be sunday. Thanks for the help!

natev8 · 1-4-13, 12:15

No problem. I hope you get it taken care of.

Installed a fuel pump tomorrow the afpr is going in and hopefully monday the pump will go in. Havent started it because I pulled the line and fpr off since I was already gonna spill some gas. Poured the gas from the filter into a gas can and it looked clean and clear. There was what appeared to be about 6 drops of something that was suspended in the gas like oil (light colored and clear but stayed together in the gas) or something but in a red can I cant tell ya if I was seeing stuff or what. Very small amount and honestly could have been in the can before.
