I have recently replaced cylinder head gaskets and timing belt truck now tries to start but hits once then floods out. Ck timing by the haynes manual and everything appears to be in time. Have good spark and I believe it is getting fuel because pl, ugs are fouling.I replaced the head gaskets because they were blown sent heads out to be checked was told heads were fine.

Have the compression tested to see if they are within specs. Try a wet test if a dry test indicates low pressure.

I have done a compression test, showing 150 to 175 on all cylinders.

Check the injectors. If they are stuck open, floodig would occur.
Ensure firing order is correct.

Injector resistance does not mean anything if it is stuck in open position.

If timed 180 degrees out it runs, then someething must be wrong with the ignition timing or firing order.

I would suggest starting from basics. Recheck the timing belt markings. With # 1 piston oncompression stroke and at TDC, check the rotor position. Ensure the firing order is correct, hope you have not reversed the rotation of the firing order.
