I ran into this once when I changed a 2000 engine with a 2001 engine. The crankshaft gear for the timing belt was different. One had 2 ears for the crank angle sensor and one had 4. To check if this is the problem, pull all 4 sparkplugs, hook them to your plug wires, turn the engine over and see if you only have spark to 2 cylinders. If that's what you find then you will need to replace the crankshaft timing belt gear.
If that's not it, and you have spark to all 4 cyls., check your fuses. It could be a fuel pump fuse or ECM or an number of other fuses.
Good luck
Dave

SOURCE: 2001 MPV Runs Rough at Idle and Low end Throttle

This could be a bad fuel injector. Lean implies low fuel to the cylinder which will cause a misfire.

SOURCE: 2001 MPV Runing Rough at Idle & low end Throttle

the lean condition is the big clue here it indicates a lack of fuel which is causing the mis-fire on #3. I would suspect a fuel injector is clogged or not getting a pulse from the PCM. ( pulse is the electronic signal)

SOURCE: 1992 SUBARU LEGACY WILL NOT START

It sounds like the fuel pump might be bad. I had the same issue, exact same one and it seems to be the pump.

its quite possibly the crank angle sensor as they do this when they heat up,the car wont start,till it cools down,you can get the resistance checked on it to see if its ok,but you will need someone with experience to do it but its not a hard job

Saab 95 1998 - wont start


The most common problem is the Direct ignition cassette, followed by the crankshaft position sensor. I am assuming that it cranks, but won't start.

Vihicle died won't start


My 92 Subaru would not start. New rotor, cap, replaced fuel filter. No gas getting to filter. When gas trickled in carb, runs like a top. I think the fuel pump out.
