2G Turns Over Then Dies

[Ferp]

So I just did my timing belt and water pump and put everything back together. When I went to start the car the engine turned over and started for about half a second then dies. Any idea?

Did you:
Note: The cam sprocket marks must not only align with each other but also with the head surface. When all sprockets are on their marks, it helps to place a straight edge horizontally across the cam shaft ends centers. Then you can just align the cam sprocket marks with the ruler.

I did align the sprockets properly.

Is fuel pressure being maintained (eg. not leaky fuel pressure regulator)?

You didn't by chance disconnect the crank position sensor did you?

I think this may be the issue.

Were you able to fix your issue? If not, turn your engine over to tdc on compression stroke on cylinder one and recheck your timing marks. If everything lines up then start checking fuel and spark.

Timing is fine, I have spark and fuel. I ran a compression and leak down test and all four cyls are good. I checked my cas and cps. I checked my drive belts, they're all the proper tightness.

if the car ran fine before you did the timing belt then it has to be something with your timing being off . pull the covers off and make sure you have everything lined up properly . make sure the dowels on your cam sprockets are facing up and the marks on the sides line up with the top of the head surface . if you use a straight edge all the marks should line up .

Or the crank position sensor, would need to take off lower timing belt cover to check

Maybe the tps and cas wire connectors are mixed up? Double check all your connectors one of them is off. All the ones around thermostat housing are correct? Got no vac leaks and all are on correct? And if you removed cas is it back In correct?

I'm going to take apart the thing on sunday. I'll let you guys know what it is then.

So I fixed it. It was the timing being off. My issue now is getting my accessory belts taut enough. My car is idling at ~400-500 where it was at 800-1000 before. I can hear my belts, all three are brand new. Is there a post on tuners with how tight they should all be?

Good catch finding that one! What do you mean you can hear them? The belts need to be tight enough not to squeal. Basic rule of thumb is around 1/2" deflection, when pushing down on the belt. What else might you have changed when trying to diagnosis the first issue? Maybe that's why idle is low.

Make sure coolant temp sensor is hooked up ..I unplugged mine when I disconnected by battery .

The coolant temp sensor makes sense. And thank you I'll try a half inch deflection. My alternator belt was squeeling, powersteering was smoking.

Squeal most likely to loose. Smoke most likely to tight and nubby by why your idle is low
