I just replaced the cam syncro and sensor on my 00 ranger 3.0 flexfuel, and I'm pretty sure my father and I did everything correctly, but when we went to see if it would start it wouldn't. It would crank and would act like it wanted to start but then it would start popping through the intake. We followed all the steps to removing and installing the part other that disconnecting the battery since it was dead(sat in the garage all winter). Is it possible that we washed the cylinders when we tried to start it, or is there another issue, fuel pressure is good, compression was good when we checked it (tripped the inertia switch to kill the fuel pump), and it has really good spark (the spark jumped about a 2 in gap on my dad's spark tester). This has been an annoying problem and it started acting up as soon as I moved back to Michigan from South Carolina where I bought the truck. Any help is greatly appreciated, as I'm to the point of takeing the truck to the scrap yard for the lously $250 that I'd get for the weight.

 

What steps did you take when you replaced it? There are two different methods I know of. One using the alignment tool and bring the vehicle to TDC, and the other which is basically a remove and replace. What steps did you take when you replaced it?

 

We took the sensor off and the tab was 180 degress from the opening, we took the old synchro out set the engine to TDC put the new sychro on using the alignment tool, then tried to start the truck, it turned over just fine it's just backfireing through the intake. My dad thinks it jumped time, and I think we did something wrong I'll try to find the link for the steps we used and post them. I hope this helps, and as always any info or help is greatly appreciated.

 

here's one of the links that we used

Also the alignment tool was kinda difficult to take off after putting the new synchro in

 

You could have the synchro installed 180* off, meaning that you were on TDC of exhaust and not compression. Remove the synchro, put it to TDC on compression and try again. You may want to get one of the alignment tools since the tang may not necessarily line up with the slot in the synchro when you are at TDC.

 

sounds stupid: Pull off the negative battery terminal cable for an hour, reattach, reset computer. I know this is a mechanical part and not electronic but it never hurts to find a solution

 

Worth a shot. I hope motorcraft parts were used as oppose to the cheaper dorman stuff. I have heard bad reviews of anything except motorcraft. I went aftermarket with my sensor and ended up replacing it twice.

 

I used a cheap doorman synchro since I really don't have the money to buy a $200 part from ford or have it put in a shop. I know I'm probably gonna have to replace it again down the road, I just need to get my truck running so I have transportation to get back and forth from work and school, I just hope it something as stupid that it was put in 180 off.
