fj60 problem. any thoughts?
We just bought an 1981 Fj60 from a board member and it seemed to be running EXCELLENTLY. Just had to change the fuel pump to pass inspection and replace a few vac lines. Here'e were the problem started.
About 3 days after the pump was changed and the truck had been driving great, it suddenly lost power on a main road after my gf shifted into 4th. We heard a loud clunk as if metel were hitting metal and as we pulled over to see what happened the engine idled irratically for about 10 seconds then stalled and was dead to the world. The tach kept jumping from 650 to 800 and then the truck died.
It was pouring rain and we were pulled over in mud so i couldn't get under the truck to see if something broke. The engine looked fine. Nothing appeared out of the ordinary. It seemed like the engine lost fuel flow or something. Is there something about the engine losing power that would cause that loud clunk?
We walked back a few hundred yards along the road to see if anything fell off the truck, but all we found were pieces of a Buick littered about the shoulder. We could not get her started for a few minutes, but as I was calling for a tow truck, gf gave it another try and the truck fired right up and seemed fine. We ended up driving her the few miles back home and took the trusty bombproof 62 instead.
Any thoughts? I am now noticing on test drives that when I let out the clutch while starting from stop, and shifting from 1st to 2nd, the truck loses power for just a split second, almost like she is going to stall, then picks right up and drives fine until the next gear shift. She seems to have less power on inclines when starting from stop as well and sometimes stalls. Because of this, driving on public roads is sketchy and she has been sitting in the driveway.
I have to say it was pretty embarrasing and frightening being stranded like that on a main road in a cruiser. Luckily we were not in the left lane.
I have not driven her more than a mile since the incident and am waiting for tune-up parts to arrive. wires, plugs, cap, fuel fiter, rotor etc.
Also, she just passed inspection at Toyota.
Any input is appreciated.
