It starts but why won't it run?

What year is it? Why did you have to replace both?

check engine immobiliser and crank position sensor . Run fault codes and replace faulty units.

Crank sensor wont have any effect on starting, Cam position sensor would. Also check all your fuses.

check for your cam sensor or crank sensor .

Check your cam and crank position sensors. Check the fuel pressure regulator and then the Fuel pump itself. This sounds stupid, but go check the gas cap too and make sure it is on tight. Sometimes it's the little things..haha. The two sensors tell where the crank and cam are in relation to each other and TDC of Piston 1. If one of the sensors is out of whack...the whole timing process will be thrown off. Most of the time if the cam sensor is bad, the car won't start, if the crank, it will start but run like ****. They don't cost much usually and your car is old enough that they should be replaced anyway. The MAF sensor would just cause the car to run rough most of the time if it were faulty or dirty. But being how generalized those codes are, it's never fun to figure out. Hope this helps you :)

Please make no guesses, just run a complete scan on the car, because if u want to keep taking off parts n replacing them u might end up spending more than you should. From what u said it could be an ignition problem, fuel related, crank sensor, cam sensor,.... Please run a complete scan on the car.

After changing the ignition module, you may have broken the communication between all the components in the anti theft security system. This is common on GM antitheft systems.

In the Nissan Quest, 1993-02, the cam sensor is in the distributor and replacing the distributor fixes it. Usually the engine runs when cold, then fails when it is hot. Not usre where it is on the 2007 Quest.

Rich Porter sells reman distributors on ebay for $200.

We talk about it on our website for Villager Quest owners.

its possible there are multiple coil packs usually one for each bank or one for every two cylinders. Or check for a ignition control module

befor in the ealier models of accords they use to be both the cam and crank sensors in the distibutor but they separated them !!!So no they are not together on your car tha cam sensor is in the distributor and the crank sensor is in front of engine or in the lower timing belt cover if it is in the timing cover you can see a wire going dow the timing cover way to the bottom on the rear side off it

hope it will help you if you have any question just wright back !!!!
