Has trouble turing over at start

no car told,maker, mode, engine
yes many do jump cam time easy if cam belt slipped, but no engine told at all.

Probably flooding possibly blocked return line (I assume EFI) or faulty TPS (Throttle posision sensor) but first check for visual problems like split intake tube, vac leak etc...

Have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure? What is the fuel pressure spec? Any applicable trouble codes? You may need to check cylinder compression?
Have you tried starter fluid? There are safety issues using any type of flammable spray. Safety is your responsibility. Some people use a little propane. I take air duct loose from throttle body, open throttle valve, spray just a little. If the engine tries to hit off the spray, it's a fuel issue in my opinion. Don't spray on any sensors.

EITHER CRANK SHAFT POSITION SENSOR OR ITS THE CAM SENSOR. IF YOU CAN FIND SOMEONE WITH A CODE READER FOR YTHE COMP. AND THE COMPUTER WILL TELL YOU EXACTLY WHICH ONE IS NOT FUNCTIONING CORRECT

Hello first of all


well i am sorry a mechanic cant figure this out its really sad. ok so your problem is your either one of two things but most likely the first one i list.

1. camshaft postion sensor
2. crankshaft postion sensor

Now that being said it most likely the camshaft sensor the reason i say that is when a crankshaft postion sensor is bad the car has very hard starts and most of the time no start issues. When a camshaft postion sensor is bad the car cuts off whil driving and can be hard to start up again.

So that being said they are both pretty cheap parts i would go ahead and replace them both and i would bet my 5 years as ford mechanic that solves your issue.

The crank postion sensor is located behind the harmonic balancer pully or right beside it here is a picture from autozone.com and description.

The crankshaft position sensor identifies position of the crankshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM).

When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown.

Designed to meet or exceed OE specifications in form, fit and function.

Global coverage for import and/or domestic applications.

And the camshaft sensor picture and info from autozone.com below.

The camshaft position sensor identifies position of the camshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM).

When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown.

Designed to meet or exceed OE specifications in form, fit and function.

Global coverage for import and/or domestic applications.

The crankshaft postion sensor is 22.99 and the cam is 19.99 so 50.00 bucks and about hours time should have you up and running.

PS if this helps please 4 thumbs up it helps me continue to help on here thanks

My truck did this after I replaced the fuel pump. Turned out to Fuel Pressure Regulator. It would crank and crank but never start. It's located underneath the black plastic manifold on the side of the injectors.

I would give a serious search for a major vacuum leak. Check around the intake manifold with an aerosol spay of starting fluid or a pentetrating oil. One of these will cause an affect of engine stumble or increase in engine speed. Check also all vacuum lines especially around the tree and all larger lines. Good luck my friend, Dana

the check gauges and hard stering are because the engine stalled, what system trouble codes do u have? if u don't know how to check these codes here are the instructions, also what is the fuel pressure.

if ur jeep has central lockin lock it and then unlock it ..........she might b sucking air inn

I broke down and purchased a new crank shaft sensor . It cost $15000 hated to spend it because everbody told me they just don't fail , and why would it when it worked fine before the motor was rebuilt. IT FIXED IT.
