No Start

[Danspeed1]

This makes absolutely no sense. I am totally baffled. About 3 months ago the timing belt tensioner broke on my 95 Monte Carlo 3.4L DOHC V6. I have been busy so I just recently (yesterday) got around to installing a new one. Car ran fine before the timing skipped. Took everything apart as I have done in the past. Set the crank arrows together, perfectly. The front bank is facing down, the rear bank is facing up. Rotated the motor, checked again, the timing was perfect. Reassembled the engine............ I have fuel, I have spark, I have an engine that freely turns over; NO START, the engine is not even back firing. Its as if the spark plugs are out. Nothing is happening. WTF?

I have reason to believe the firing order is wrong, however I cannot seem to find a correct diagram, or at least one that works for my vehicle.

Here is why I think something is wrong with the firing order.

135
246
Front Of Car
Order: 143625

Ok, I had the firing order incorrect at one point and it sounded like it wanted to turn over. It was burning fuel. Finally I corrected the firing order, and I have nothing again.

The firing order is 1-2-3-4-5-6 on the plugs,,, NOT the numbers on the Lower Intake Manifold..
As far as timing the cams,, the proper way is to use a dial-indicator to find TDC on Cyl #1 and set the flats up there... Most people don't trust those arrows... Here is a link to the timing job:

You DO realize that you have to loosen/remove the locks on the Cam Pulleys to set timing???
Good luck,,

I think the order he has there ("Order: 143625") is on the coil packs, which I believe is correct to the best of my memory right now except I usually go 146325 (not that it matters).

Edit: woot! post 2800

That's not how I have done it in the past. This is my 4th time so I figured it'd be cake by now. I set the crank pulley arrow to arrow. then I adjust the forward bank (ones closest to the front of the car) down. Then I I set the cam flats on the rear bank up. I spin the engine around one revolution until the front flats are now facing up and the rear ones are facing down. I check the front ones to make sure they are facing up "properly" in alignment. Then I flip the motor again, check the rear ones once more; finally I pull the pin on the tensioner.... and then just to be extra special sure I flip the motor twice more check to be sure the flats are aligned face up and the crank is landing with the arrows facing one another. I have done this process a few other times and have never had an issue.

why would nothing be happening? Shouldn't this thing back fire or something. Literally nothing is happening. Its like the engine is getting no spark, however it is!

P.S. I just replaced the plugs; no difference.

1. What is the cranking compression?

2.There's a difference between the firing order of the ENGINE, versus the firing PAIRS of the three coil packs.

ENGINE FIRING ORDER: 123456
this can also be displayed as:
1 2 3
4 5 6

COIL PACK FIRING PAIRS 1 and 4; 2 and 5, 3 and 6. Note that the coil pack firing pairs are the same as the firing order when split and viewed one above the other.

You must have the two plug wires on each coil connected to the correct pair of cylinders.

Guys, I have been leading everybody in the wrong direction. Sorry. I emptied a can of brake parts cleaner and starting fluid into the engine and had it running for a good 15-20 seconds. So at least I know the timing belt is right. Even though I am getting fuel pressure at the fuel rail, It seems as though the fuel is not making its way into the engine. What are possible causes of this?

I now know its def not the belt or the plugs because I had it running. I am wondering if from sitting the fuel filter clogged up or something.

I have a fuel injector test kit... I tested the injectors, they are not energizing when I turn the key.

Now what?

DG

[bszopi]

Forget to plug a harness back together? Or a blown fuse?

[Danspeed1]

Which fuses are involved in this mess?

I can't remember disconnecting a fuel injector related harness.

DG

[Incydowt]

check to be sure your EFI Relay is doin its job, should be in main fuse box under hood, the main injector fuse is as well

Finally got it, PCM was slightly loose. Tightened up the connection and the cars runnin like a top.

Thanks for the support,

Gotta love free fixes
