I'm having trouble getting my 92 K-5 started after I replaced the motor. I have to give it a shoot of starting fluid then it runs. I'm at a loss, I can't figure out why its not getting enough fuel at start-up. I replaced from the pump to the reg. Can someone give me any help or tell me what it could be. Thanks.

 

Try and get someone to crank the engine while you are looking at the throttle body. While cranking, see if the fuel injectors are spraying any fuel.

 

have you got oil pressure?, cause the oil pressure switch wont supply fuel until proper oil pressure is built up, just somthing to check.
