I just replaced the cylinder hear and timing belt in this car and now there is no spark. Everything is connected properly and it turns but no spark. It ran before so I was thinking matbe the crank angle sensor died? I don't have a manual so I am not sure how to test it.
Do you
have the same problem?

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor /distributor pick-up coil, ignition control module, ECM, Ignitor camshaft and crankshaft sensors- Note: If it doesn't apply disregard it

There is no distributor only a crank angle sensor the picks up off the camshaft and the coils so this didn't help me at all.

Have you checked and test the ignition control module

No didn't check the module as the car was ruuning before I tore it down last week to replace the cylinder head. So how can I check the module as I don't have a shop manual for this car.

It ran before-backtrack all wiring connectors that you have unplugged-also you need a ignition module tester to check the ICM

The CPS tracks the position of the pistons and engine speed sends it to the computer and in turn fire the coils

One way to check if the DIS ignition module and its crankshaft sensor circuit are working: connect a halogen headlamp to the spade terminals that mate the DIS module to the coils. A headlamp is recommended here because it puts more of a load on the module than a test lamp. If the headlamp flashes when the engine is cranked, the DIS module and crankshaft position sensor circuit are functioning. Therefore, the problem is in the coils.

If the headlamp does not flash, or there is no voltage to the module or coil pack when the engine is cranked, the problem is most likely in the crankshaft sensor circuit. On most vehicles, a bad crank position sensor will usually set a fault code, so use a scan tool to check for a code. Or, check the crank sensor itself.

Thanks now you mention a crankshart sensor and I this has a camshft sensor so would it have both of them or just one before I go trying to find the crankshft sensor. Now seeing that I don'r have any shop manual for this car where would I find the DIS module and which termals do I use?

You got both the CPS and CMH sensor-The CPS is on the front of the engine and the CMH is on left rear of engine. I don't think you have a problem with the DIS module if it was running before you did all that replacement-sounds more like wiring connections.

Be advised this can drag on w/o a repair manual-you can download here to get one at a cheaper price.

The CPS is located at no. 38 see pic

The crankshaft position (CKP) sensor (Figure 54) is a magnetic transducer mounted on the engine block adjacent to a pulse wheel located on the crankshaft. By monitoring the crankshaft mounted pulse wheel, the CKP is the primary sensor for ignition information to the PCM. The pulse wheel has a total of 35 teeth spaced 10 degrees apart with one empty space for a missing tooth. The 6.8L ten cylinder pulse wheel has 39 teeth spaced 9 degrees apart and one 9 degree empty space for a missing tooth. By monitoring the pulse wheel, the CKP sensor signal indicates crankshaft position and speed information to the PCM. By monitoring the missing tooth, the CKP sensor is also able to identify piston travel in order to synchronize the ignition system and provide a way of tracking the angular position of the crankshaft relative to a fixed reference (Figure 54) for the CKP sensor configuration. The PCM also uses the CKP signal to determine if a misfire has occurred by measuring rapid decelerations

I signed up for the mitchill manual and after hours and hours of trying to find any actual information on how to diagnose or test for no spark I came to the conclusion that this manual was useless. It referred to tests that did not exist in the manual so how do I get a refund for the money I wasted on getting that manual downloaded?

Reference to refund -you must contact Mit1 -as per your problem did you put engine no.1 piston on its compression stroke/TDC and line the camshaft and crankshaft markings up when you replaced the head and timing belt If so and wiring are okay to include the cam and crank sensors-The last place to look at is the computer

Finally I am able to get back in to continue with the discussion. Please tell me where the computer is located as I could not find any diagrams and pictures in the mitchill website. Also how do I contact Mit1 for a refund?
Thanks
