Tested fuel pump which is at 56psi constant. Both injectors were bench tested and have good streams not clogged. What else would you guys recommend?

I greatly appreciate all your advise.
I have another question... can somebody tell me what the fuel pump pressure should be? I just want to make sure my pump is running good.

I Was ridding then out of the sudden engine started to bog down. red light on dash came on and gave code p0005. Can anyone help me out with this and tell me how to fix. 2016 zforce 800

You are correct it is a 2016, I had a typo... valve lashes are checked and correct, we did an engine rebuilt 3 weeks ago. Compression is fine. Engines runs great. Fuel pump is working fine. Replaced fuel filter and air filter. Runs great in Low and Reverse, but lacks power on High gear. Will only run on High gear around 17mph. Any more suggestions?

Dear Friends,
I have a problem that puzzles me... my 2006 ZForce 800 EX is not running fast at High gear, reaches about 17mph. It's got 566 miles on it. I'm wearing seat belt and light on dashboard is off. The diff lock seems to work fine, at least on the dashboard lights up correctly 2wd, 4wd and lock. When shifting to dashboard reverse light turns on, goes off when in L or H. Perfectly runs in Low and Reverse. While in neutral it reaches 7500rpm, which indicates the engine is running good. There seems to be a limiter somewhere that causes the unit not to run fast. Any suggestions? Need help. please.

Timing was off.

Finally got it running... thank you very much.

Never mind. I got it!!! Thank you very much, greatly appreciated. I'll keep you posted.

Sorry. Tried to open the link and it comes as: "Shared file not available"
Could you please be so kind to share it again? Thank you very much.

Unfortunately, we do not have a service manual. Can you guide us as to where to find one? Is there any link in this forum that has one or has the specs? Or do you have a PDF, that you can attach here? Your help is greatly appreciated. Thank you.

We checked spark with a spark tester. We checked injectors by taking them off and see them spray. Fuel pump is working. Therefore doubtfully it is the crank sensor.
I will check on the valve timing. How can we check the proper valve timing and can I have the proper valve clearance.

Dear Friends, hopefully you can give me an answer to my dilema. Have a ZForce 2015 that cranks, has spark, replaced fuel pump and injectors and still will not turn on. Compression is at 128 and 127. Replaced gas. Throttle assembly does suck air in. It's a 2015 shows no codes. I'm puzzled any suggestions?
