Need some advice from someone experienced in 90 cruisers.
I'm struggling with a really annoying problem that I can't fix for the life of me.
I've asked here before so maybe you'll be familiar with this a little.
This is a 99 year 90 cruiser not common rail.
The problem is that it takes a long time to start (10+ seconds) and when it starts it's at 400-500 rpm and doesn't respond to throttle or anything for a while. Usually after a few minutes it starts normally and is at normal rpm (830). After that you can drive it and it's good and has a lot of power, good response and everything except when it's fully warmed up then it goes completely haywire. Every time I go below about 10km/h the revs drop to 500 and it won't respond to throttle, so I either have to go to N and rev-match and then shift into drive. If that doesn't work I'm just stuck until it recovers which takes a different amount of time. Pressing the hand pump on the filter doesn't help. It starts quicker if I turn it off and on but it doesn't make much difference.
What I've done:
- Changed the oil pump 3x
- Changed the injectors
- Changed the oil housing (filter and hand pump) 2x
- All hoses to and from the tank.
- Glow plug and bracket there.
- most of the wires in the engine bay (either fixed or replaced)
- replaced most of the sensors (Tps, Turbo sensor, etc.)
- The time is 100% correct
- The time on the job is also 100% and I've tried changing it to no avail.
- ground is good everywhere
- tried 3 different computers
- All engine codes gone
- I've bled the entire system (using clear hoses and there's no air).
Please leave a comment or PM, I'd be very happy to get some advice, I'm really giving up as you can see, I've done quite a bit.
