No. It should start within 2 or 3 seconds. Can you describe the injector noise you hear just before the engine starts? When it finally does start, does it idle normally?

That sound exactly like what is happening.

I have a battery booster on it.

The oils pressure sending unit is most likely bad. It gets to a certain pressure then "shorts" out giving you a higher reading.

Is this on when you are trying to start it? How is the fuel in the bowl? Is it draining back when the truck is off? Oil level and right type of oil?

Remember I am inside a van with the dog house off. I can hear everything. I hear a real rapid clicking or electrical snapping going on every time just before it starts.

Just for the heck of it check your grounds. If a ground is loose or dirty you may here some of the relays chattering. As the current flowsthrough the "bad" ground it heats up and makes contact.

Is that the sensor on the HPOP cover left side?

Clicking or chattering relays is a good sign of weak electrical connections. Either bad batteries, bad connections or maybe a bad grounds.

I believe the oil pressure sensor is the one on top of the HPOP reservoir and the oil temp sensor is the one on the side.

I understand you're sitting a lot closer to the engine in the van, but I've had my head under the hood during start ups and don't recall hearing these clicks.

I don't think that sensor is your slow starting issue. I agree the clicking sounds more like an electrical issue and that could easily be the slow start problem.

Man! This engine just can't get right. I still can't figure out what caused the left bank on the original engine to over heat so bad it melted the valve cover gasket and stick 3 pistons. The right side is perfect. Now a new engine and I'm scared that the old problems are going to make this engine self destruct.

I have had scaners on this limo coach and the only this that comes up is the oil back pressure problem. Which I don't think is very important. How would I figure out the possible electrical problem?
