You need to check for power as soom as you turn the key. you loose power afterabout 7 seconds after turning the key to "ACC position". there is a relay in system that shuts off tha power to the pump after about 7 seconds or so. personally I think that you have an issue with the sending unit. xterra has a campaign for sending ubit replacement, because they corrode on the inside of the connection on top where tha connector plugs in under the seat that you took out. This is what you will do: have someone crank the vehicle as you move the 2 wire connector on top of the gas tank. it may start. If not, then take your vin number to the nissan dealer and see if it applies for the sending unit replacement. you may even need new gas tank which is covered under the campaign if its too rotted on top.

98 mitsubishi montero, trying to by pass security, now wont turn over, maybe the starter lockout, but cant find diagram to trace correct wires

With the connector halves close together can you tell which wire goes into the connector? Its probably the same color, but check anyway. Once you are sure you can follow that one back to where it comes from and check for power

How was the horn kit wiring harness installed? Was it patched in? Did it have its own wiring harness? Trying to figure out how that kit could have had any effect on the starter.

When the key is on do you have accessory power?

2003 nissan altima hesitates when I start to excelerate

I assume that you have a 4cyl engine, and that problem is from the engine. there are two places that you can check, remove all ignition coils and see if there is any sign of oil on it, if it does, replace valve cover gasket and clean that coil. The second place is, a little difficult to check, look for the crank sensor, it located on the right/rear/lower of the engine (if you are standing on the driver side, look toward the rear of the engine, it's on your right and on the bottom of the engine), look for the harness, you will find a plug with a green tab, push it in and then pull the plug out. Any sign of oil, replace the sensor and clean that plug. Good luck!

2003 mitsubishi outlander died at stop light. wont start. turns over and has a full tank of gas. is getting fuel to engine.

very poss it could be crank sensor ,broken wire ? timing belt? advise installing scan tool that reads live data check eng rpm on scan tool see if shows eng rpm while cranking , poss remove upper timing belt cover make sure is turning and not damaged, poss computer related problem or power to eng systems would have to check for power at fuel injs and check for ground pulse with logic probe or led test light if crank sensor ok also check for spark at plugs with special plug tester and check codes first

Turn key wont start- it cranks

check plug for fuel pump in harness near gas tank for corrosion and it may also have seoerated wire where it comes out of connecter the seperation may be from pulling on wires when pump replaced insulation may look alright because it streaches.
