So I have a N/A SD33 in my 1983 MQ Patrol, it is on 24v. Last month while on the AZ Run she failed to start on the last morning. After checking voltage and ohms we found out glow plugs were shot. We were able to start the truck with a shot of starting fluid so we could finish the last day and get out of the mountains.

I recently put in new 24v glow plugs which are working fine and getting the correct volatge. They are set up on a push button so the auto glow plug timer is not in this truck. After doing this I still can't get the truck started so I started trouble shooting other things. She is getting fuel to run so it isn't a fuel delivery problem. Air intake is fine and clean so has plenty of air. Truck runs good when I get it started so it isn't a compression problem.

What I have figured out is the injection pump controller is not moving to the start position when the key is turned on. It does however go to the run position and also to stop when the key is turned off. I even checked voltage and ohms to/at the controller and it is fine. So I think ok, controller is toasted. This leads me to think I can start the truck by moving the governor to the start position and the truck will start. So I get a friend to help me, we glow the truck and I know glows are hot enough to start it, I move the governor to the start position, he turns it over and nothing. It just cranks over and doesn't even try to fire up.

I can start the truck very easy if I glow it the right amount of time and then shoot a tiny little shot of starting fluid into the intake. I know this is bad, real bad and I shouldn't do it. Trust me I am using the smallest amount of fluid possible and only doing it when I have to. But there is no other way to currently start the truck.

So does this mean my 25year old pump controller and governor are shot? If I put the governor in the start position but the truck won't start this must mean it is not supplying the "excessive fuel for starting" as per the Nissan manual? This is a very simple motor, I clearly understand it but am I missing something here to trouble shoot?

Never had a problem like this before only bad plugs or injectors. The truck ran and started fine up to the last day of the 4wd trip. Any help would be great before I source expensive parts....sorry for long post but I always feel the most amount of info is the best!

If you hold it in the start posistion you have to realize that there is only one correct spot for it to be in, has to be fairly precise.
