car has power but wont start help

[jdmbwoy24]

I just spent my whole day yesterday doing a whole 120 k tune up and did all the major deletes but when I was done I went to start the car and nothing happened...the seats worked but everything else didn't so im guessing there is a fuse or ground some where that I am missing ..can some one post up pics or explain to mi step by step where each ground should be or what else could cause this asap cause the other write ups ive seen are not that good I need to fix this by this week or im towing it to the z shop.

First, when you go to start it, do you mean that literally nothing happens? Or it cranks but won't start?

If nothing happens at all (no noise), its probably something related to the battery, starter, trans not in Park, etc. If it cranks but won't start, then its something like the CAS, PTU, TPS, MAF, etc. not working or not connected right.

As for grounds, there are 2 ground locations on the upper plenum:



One ground goes to the bolt on the passenger side (left circle in this pic) and 2 grounds go to the bolt on the driver side (right circle in this pic). Besides those two, there is the actual battery cable that grounds on the firewall right behind the battery and then onto the transmission.

I crank it and nothing happens it probably my battery because my car is 5speed my starter is brand new or not connected right ..after it didn't start I didn't even bother to try again because I was so tired im just gonna get a fresh battery and start again tommorow

and I have the ground there already

Yeah if you had a voltmeter/multimeter you could check the battery voltage. Should be above 12. Most likely yours is below 12 and isn't giving the starter enough juice

Also FYI, Walmart sells batteries for ~$85 with a 3 year warranty.

Before you go off and spend $85-100 on a new battery... does it make any noise when you try to crank it? If it does it could be the battery. If not it might be the relay located under the driver side front fender. It gave me hell a few months ago and its one of the most simple and cheap fixes
