No spark, no fuel, no start after heads reinstalled

Hello,

This sounds like you could have a problem with your vehicle's Crankshaft Position Sensor. It is responsible for sending your vehicle's Power-train Control Module [PCM], or "computer", with a signal telling it where the engine is in it's 4 stroke cycle so it can synchronize and fire the fuel injectors and spark plugs. Here is a generic guide on how to replace a crankshaft sensor in a vehicle down below:

In the diagrams down below I have included a picture and diagram of the CKP in your vehicle. Please go through this guide and get back to us with how everything turns out.

Hello,

Could you take a voltage reading across your battery terminals for us Please get back to us with what you find out and we can go from there.

Hello again,

Okay, your vehicle's battery is good. In the diagrams down below I have included all of the electrical specs for the sensors in your vehicle as well as the diagnostic troubleshooting guide for the CKP for your vehicle. Please go through these guides and get back to us with what you are able to find out.

Hello,

There is an issue of an open or unwanted resistance in the Controller Area Network[CAN], or the wires that go to the Data Link Connector[DLC]. In the diagrams down below I have include both the Original Equipment Manufacturer[OEM] wiring diagrams and the wiring diagram for your vehicle's DLC. I have also included guides for finding opens, and unwanted resistance in an automotive electrical circuit by the way of Voltage Drop, the preferred method for finding unwanted resistance. I have also included a generic pinout diagram for your vehicle's DLC. All DLC's are universal and required by law to be exactly the same, so a pinout chart for one vehicle will be the same as any other. You will need to use a Digital Multi-meter [DMM] to go through these guides, so here is a link below explaining how to use one:

Please go through these guides and report back with what you find. Happy Holidays.

Hello,

What fuse is blown in the underhood fuse box? Is there any way you could take a picture of it and upload it here for us?

Thanks,

Hello again,

Fuses blow because there is a short to ground in the circuit[s] that the fuse is protecting. This happens because of Ohm' law, the laws that govern electricity. One of Ohm's Law's states that if one of the three properties of electricity remains constant[Voltage - Voltage in a vehicle remains steady at battery voltage] and one of the other two goes down[Resistance - Resistance goes to zero as there is a direct path back to the battery negative terminal] then the final property must go up proportionally[Amperage - Amperage goes to battery amperage]. The fuses amperage rating is over taken and "POP", the fuse melts creating an open in the circuit[s], protecting the circuit[s] just as it was designed to. So, the fuse will continue to blow until the short to ground in the circuit[s] it is protecting is repaired. In the diagrams down below I have include the passenger compartment and the engine compartment fuse box diagrams with call outs. Please get back to us with the fuse that keeps blowing and we can go from there.

Thanks,

Hello again, Okay, so there's the problem. You have a short to ground somewhere in that circuit. The circuit provides power to the ECU, or "computer" for your vehicle. This is why your scan tool cannot link with the ECU. This is going to be the ECU3 fuse. In the diagrams down below I have included the Engine Management wiring diagrams with the ECU3 wires highlighted for you and a guide on how to find a short to ground in an automotive electrical circuit. You will need to use a Digital Multi-meter [DMM] to go through these guides, so here is a link below explaining how to use one, if needed:

Hello again,

Yes, the problem is a short to ground in the circuit[s] the the ECU3 fuse is protecting. In the last reply that I sent I sent along the wiring diagrams of the ECU3 circuit with the wires highlighted and a guide on how to find a short to ground in an automotive electrical circuit. Please go through these guides and get back to us with what the short to ground is.

Thanks,
