97 mpv died while driving. getting gas / spark but know start. seems to be cranking very easily. rotor turns when trying to start. maybe jumped time? or blown head gasket. i need to check the oil. if no water in oil, then what. plugs seemed to be soaked with gas, so obviously flooding out, but is definitely getting spark. things replaced- filters, FP, tune up regulars,.....could it be TPS or IAC valve?

If it sounds to be cranking much faster than it did before or just an overall different sound then a good chance that the timing belt has jumped. That is unless the abnormally fast crank is due to low compression caused by washing down the cylinder walls with the fuel. If it was cranking fast or abnormal from the very beginning of this whole event then a check of the cam/crank timing would be in order.

Testimonial: "Excessive fuel could deffinately be the cause of the low compression sounding cranking. If it is, then is it the FPR or CPS?"

97 escort lx will not start, i have fuel spark and timing belt is good it cranks and sputters like its about to start but wont fully turn over every so often i can hear a pop sound when i try to start

Sounds like the timing belt has jumped some teeth. that pop you hear is detonation as the cylinder is firing while the piston is on it's way up.

Saturn died while driving and now won't turn over

check to see if the cam shaft is turning while cranking the engine (broken timing belt) run fault codes to find faulty sensors.

97 mpv died while driving. gets gas and fuel. is it the timing belt?

When you crank the engine does it sound whinny? If it does then yes its the timing belt, the only real way to tell is to remove the distributor cap and crank the engine and see if the rotor of the distributor turns if it turns then its not the timing belt. Here is the thing 1997 Mazda MPV is identified as a interference engine meaning that if the timing belt broke it is MOST likely to do engine valve damage, So you will have to pull the timing belt cover and inspect the T-belt you will know if its broken when you push on the belt and there is no tension on it,

97 200 miles 4.0 grand cherokee dies backfires starts and sometimes it doesn't start right back up. strong fue; smell too. have replsced o2 cam sensor ignition switch fuel pump acoil thing. This seems to...

Sounds like your engine jumped time. I would match the Top dead center line on the crank with the TDC line on the block . Remove the number 1 spark plug. being VERY careful use a screw driver to enter the spark plug hole. It should stop right away . if the screw driver goes almost all the way in? Do 1 more revelution on the crank to the Top dead center mark. Now that you have achieved this. Take the distributor cap off. The rotor should be on Number one plug wire on the cap. If it isn't far off? loosen the distributor screw and turn the mechanism until the rotor is at number one plug wire. replace the cap and plug and try starting it. If the problem is still present? Your motor needs a timing chain.

Driving down the highway and car died. Have gas yes. Spark? Do you think timing belt or chain broke? How do I find out?

To check timing belt or chain, remove distributer cap and turn engine over. BRING TO TOP DEAD CENTER AND SEE WHERE THE ROTOR IS POINTING, #1 cylinder? IF NOT SPEND ENGINE ONE TURN, pointing at #1? If not then you may have jumped time. Take a scoket that fits the crank and turn the engine by hand. The rotor should start turning right away, the mor you move the engine without movement of the rotor shows slack in chain or belt.
Another possiblity is that you might have a crank sensor gone bad. Check for fire at the spark plugs. Take one out and, while the plug is laid on the engine, spin the engine, it should it should spark. Either way shows that the engine is not firing. Next is to do a compression check, ther should not be more than 10% difference between the cylinder. If no compression, you have an interfearance engine and jumping timing will bend the valve. Hope this helps.

1985 monte carlo ss cranks but does not start

check that rotor, mine was arcing through to the distributor shaft (it was inferior part, junk brand) A little throttle? or punched it hard around the corner? 165K check the timing with a timing light ... maybe the timing chain jumped sproket ...
I actually had the exact same scenario after tune up twice with my 1970 Dodge Dart 318 ... first time it was the rotor .... 2nd time (years later) it was the timing chain
