Quickest way is to remove the distributor cap and see if the rotor button points to the no 1 lead ( mark in body) at top dead centre. If it is past or before it then the cam timing could be out. Next best is to remove no 1 plug get the piston on tdc and check valves on no1 cyl for valve over lap That is a small movement clockwise will open inlet valve and a small movement anti clockwise will open exhaust valve.

SOURCE: 98 dakota engine dies

timing chains either go out or not go out, there is no such thing as an intermittent problem with a timing chain, what about the ignition module? it is sensitive to heat, and like the crank and cam sensors can cause your kind of problem. U did not mention fuel pressure either, electric fuel pumps can stop from heat when they get near the end of there service life (100,000), this is even more common if the fuel tank is run below 1/4 tank allot, this overheats the pump in the tank because it is not covered in gas, that is how it is cooled.

when you replace crank sensor the crank sensor is going have to be reprogram or relearn before car will crank.

SOURCE: back fires under load and is sluggish at times

Backfires means that pressure is high and gas is igniting before it should. This happens under load because loads require more horse power than torque. Although the 6cylinder should normally be OK with 86octane. Try something higher and see if you get the same issue. Higher octane gas means it can handle higher compression and thus would eliminate the problem.

If you are already using high octane, switch gas stations for about 2weeks (enough to clean out old gas) if you regularly use the same gas station.

Also, the compression should be presented as a ratio. Cylinder position at start of stroke vs cylinder postion at bottom of stroke (not exact but something like this). 10:1 is about right

SOURCE: Is it a timing belt or chain on this motor? I want

Hmmm...thought I already answered this question--it's a chain. Would you like the procedure to change it?
You may be able to check the timing marks without taking the cover off. You would have to take the vibration damper off and remoive the crank seal with a seal remover. Then use a flashlight to look up at the marks on the gears. OK?

Not god to use starter fluid, gas in a bottle works. If it starts that way ,my guess would be the fuel pump.

98 Chevy blazer won't start up but will crank ,,


Try giving it a shot of starting fluid. You don't say if it's actually firing. If it tries or runs for a few seconds off of the starting fluid then try changing the fuel pump relay. It's inside of the glove box on the left hand side behind the little door. If that doesn't work it's most likely the fuel pump.
