I just got it ot of the paint bay and was thinking about replacing the timing belt because its been off the road for 4 years and the belt was replaced many years before.
It was running fine and then just shut off? I thought maybe out of gas because the gauge was jumping around a lot as I drove it around the yard? I put 6gal in and started to crank it. It was taking longer than norm on starting when out of gas(redid the gas tank and sealed it). I tried again and again and then the motor would turn over a few times and then stop like hit hit a brick wall? I tried two more time and the same? So I gave it up for the day!
To me it acts like a normal old V8 motor that the timming is off?
Any ideas before I go after the timing belt? I kind of like to know what happened? Or was it good timming the belt went while it was at idle and not going down the road?
It may be just old, dirty fuel in the lines and filter.
The lines and filter are all cleaned out and all fresh gas. I removed the gas tank and cleaned it a sealed it. That was months ago and has been running fine and even better the last month like the computer caught up with all the new parts and new gas and just run as good as new but thought I had better do the belt because its been so many years and I am guessing at over 12 years on the belt but only maybe 50,000 miles. Its been off the real road for years.
It was the fuel pressure reg. The diaphragm busted. It was sending gas into the intake and causing a flood condition and stopping the motor from turning over. So there goes another $100 but better than I thought might have happened!
I had bought one from Advance for around $60 but the motor keep surging so I put the old one back on and it did fine but not any more so I hope the higher cost ones will work right because the cheaper one didn't for sure unless someone knows why the new one didn't work?
