Okay so last summer I purchased a Mazda rx 7 with 80 k miles in excellent condition . It was kept in a garage that stayed room temperature all year long . The car sat for 8 years was started and ran on the regular except a couple years owners got lazy . I brought it home and I have done a lot of work getting it ready to run . How ever I ran into one small problem that might have messed everything up . My heater core went bad on it so I changed it with a brand new one . My dad helped me then the heater vent door motor went and replaced that as well . No here's were it gets crazy I drove the car to work one morning the cars been running great but my coolant was low no leaks so I added more same thing for the rest of week every day finally I figure out one of the hose clamps were tight enough dads fault lol . By this time the weekend comes up I pull into my father rpms reving up and down smell like a burning plastic smell or rubber something's fried . And cookainbehind my seat both sides more the passenger side and a lot of it four or five inches o. Passenger side . After that day nothing's working and fuses are blown . Is it possible that the coolant got in the ecu board on passenger side and fried it ? Need help please guys . After this no one else will be helping me with car I do everything myself .

 

No offence, but is English your second language? I say this because you have very poor sentence structure and grammar.

It is possible you that water got into the CPU. Try pulling back the carpet and examining the CPU.

 

Or that no wires/loom was pinched from your work.

 

Sorry for the poor structure bro . I am using my iPhone with my daughter climbing all over me . Also my phone has a mind of its own . I was never the best at grammar anyways . However you get what I'm saying thanks for the help no reason to be a stickler . Thanks ...

 

Okay so here are some of the signs that happen before the car went totally dead. My seatbelt buckle light wouldn't work . It was stuck on . Fuses popped here and there . The clock stopped working . The lighter stopped working and the stereo stopped . I check ed for power at the coil packs and nothing . However if you turn the key the starter and fuel pump still sound like they are working . How many cpus are there ? Witch ones should I look at first ? Or is that the ecu shitting the bed ?
