I need some help, I installed an ls6 intake on my 98z
, but in the process of removing the ls1 I ripped the MAP sensor 3 wires from the conector i rewired it installed everything back car started up but ideled at 3k Itook it for a ride and It stayed at 3k while idleing, turn it off after Igot back now it won't start it'll turn but won't start what could it be?

vacuum leak or you messed up the map sensor. is the car throwing any codes?

hot98z28

Yes I removed the intake and redid everything to make sure it didn't have any vacum leaks. T
And the only code it throws is the map sensor low voltage. I've erased it but seems to pop back up everytime Iturn the engine, I'm on the way to buying a new sensor

munn79ta

new map sensor fix your issue?

hot98z28

I haven't baught it yet, Iget paid till Friday ill post the results

hot98z28

No it didn't help Ichecked for spark and I'm not getting any what could the problem be? It also threw the map code again with new installed. It's driving me crazy, ima check all the wiring again

munn79ta

yea has to be a wiring issue if the map sensor is new. also make sure you have all the connectors plugged in. im not sure if the map circuit is messed up if that wont let there be spark. just double check everything. what map sensor did you buy? oem for a 98?

sounds like your wire fix isnt working...

hot98z28

Yes oem map sensor, Iredid wiring and it stoped throwing the code but it still won't get spark Itested the conectors going to the coils and they do have current, what could have caused it to not throw spark? Could the vats on the key thing have broken and be the reason it won't fire?

The car started when I first installed the intake but idled @3000rpm took it for a ride a didn't help, I even turn it off and turned it back on when Igot to my house Iturned it off to replace tb since the new one had the bigger hole on blade for cam, Ithought that was the idle issue, but after that it wouldn't start again

munn79ta

how are you checking for spark? are you checking all the coils? were you getting spark before changing out the old map sensor? maybe you shorted something out?

hot98z28

I removed a spark plug and had a buddy crank the car while Iheld it to ground, Iused a metter to check if there was current in the wires going to the coils and there was, Ichecked for current to the map and there was, Icant belive Icant get this car to start

munn79ta

if the circuit to the coil is ok and you have power i would assume the coil is bad. i would check multiple coils for spark.

PROBLEM SOLVED!!!
i decided to change the cam position sensor before sending the ecu to get repaired
and noticed the wires had been crimped by the manifold took them apart cleaned them up reinstalled everything and bam it fired right up!!! Thanks everyone.
