ok i was wondering if an obd1 h22 has a crank sensor? If it does not can you put a crank sensor in it?

They have 3, just like all other H22s.

Where they are is the more relevant question, I suspect.

Every vehicle produced has some form of crankshaft position sensor that either reads off the pulley or the flywheel. It helps the ecu determine TDC #1. Even with it failing, the computer will back up with the cam sensor(if equipped), h22's have one. You will just experience long crank times. Takes the ecu a little bit longer to determine TDC #1. Then it'll fire. Once running the ecu bases all timing ignition and injector of the cam sensor. Hope that helps.

All of the OBD1 H22s had all 3 crank sensors in the distributor.

so if my car cranks for a while before starting even when warm, i can suspect the crank sensor being the culprit?

Quite possible yes, not very often they fail on the h22's unless it's a high miler
it's something else then, I have less than 100k original miles.

Long crank time eh? Plugs with to large a gap will do it, any large resistance in secondary ignition. Check for cap and rotor corrosion. Fuel pressure and volume is a must check too.
