Did you sync up the engine properly when you reinstalled the timing belt/chain? It is possible to be on the marks and be 180 degrees off. Align the timing mark on the crankshaft then check the rotor position.If it doesn't point to number one wire terminal position roll the engine over until the crank lines up to the timing mark again. The distributer needs to be pointing the wire terminal that goes to number cylinder.Any other position is unacceptable and you can't simply turn the distributer to number one either You need to retime the crankshaft to the camshft making sure that the distrubitor points to number one and both valves for number one cylinder are completely closed.

Your flywheel sound like it has hot spots on it, making the clutch chatter. You might need to pull the flywheel off and get it re-surface. This is like turning your rotor, or brake drum. If you pull the flywheel, you will see discolor spots on your flywheel. This is called hot spots, and will make the clutch slip.

On the other problem, have you changed to fuel filter and fuel pump. It almost sound like your running out of fuel????

You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.

1987 Nissan Pickup with Z24 Engine, Started to have rough Idle when Cold, I put new plugs all 8 Cap and Rotor, Checked hoses for Vacumm Leaks, When It warms up It Improves a little.


The coil wires may be inter changed or the one coil might not be friing. the intake cam in the most senseitive so if one coil is'nt firingyou can switch the coils as they are the same part and put it in the other coil wire and the other set of primary wires and put it all back together If it now fires on the exhaust side the coil is bad and just but a new coil if it still only runs on the same side you may be having troble with the distrubuter pickup. If you are a reman distrubutor from an auto parts store is the way to go as they have a warrentee to be good and the common man has the skill or the tolls to rebuild the distrubutor with a new pickup.

1986 nissan pickup z24i. will run when spray start fluid but wont stay running. just installed the engine


Did you hook all the lines for the fuel pump up when the engine was re-installed? It is definitely a fuel issue. Disconnect the fuel line and crank over the engine to check for fuel supply.

1986 (11/85) z24 model 720 Pickup. Vehicle has only 75K, which means it sits for weeks between usage. Terrible bucking and stalling, usually under heavy load (steep mountain roads). Sometimes can run...


Try running a good fuel system cleaner through it. Sitting alot allows condensation to form in fuel tank. Also condensation forms on plugs, etc... Pill plugs and inspect, but do run system cleaner regularly.

I have a 1986 isuzu pickup with 2.3 eng i cant find the timing mark on the oil pump pully where is it


Oil pump has no timing mark. Just get the crank and cam marks aligned. Make sure the belt is tight on the right between the cam and crank sprockets when they are on their marks. Then apply tensioner. OK?

No spark at plugs on a 1986 chevy pu with 350 is the coil bad or something else


to test whats wrong you need a test light 12 volt. It's an ice pick like tool with a clear handle and a ware with an alligater clip. hook the clip to ground near the ciol then with the key on the ciols small wires will be hot ( lights the light ) unplug the small wire plug at the coil and one wire will be hot the other cold. the one thats cold connect the test light and reconnect to the coil. crank the engine before cranking with the key on it should be lit cranking it should flash off and on quickly. All of this presoposes that the battery is well charged and cranks the engine good. if it just stays on then you need to verify that the distrubutor is turning, ( cap off look it it with it cranking it should turn if not the timing chain whent out. no flash and the distrbutor turns the crank senser 9 DISTUBUTOR PICKUP OR THE INGTION MODULE failed any of the wires can break too. Most auto parts stores can test the module before you buy a new one. module failure is common well motor no start. the pickup is not as common and if your not a regular mechanic then changing the distrubutor is easier. make sure that you put the new one in the same as the old one or it won't run. turn the engine till the rotor points straight to somewhere (front) pull the old on watching it turn as it comes out so you can turn the new one in at the same place put the cap back on and fire it up. The rebuilt distrubutor will have a new pickup and module. The coil can fail but not like a light switch. if the the ciol has power and the other side flases and theres no spark the coil is bad.
