1995 Maxima - Won't Start Once Hot

[amorak]

Hi guys,

my granddad's '95 Maxima is having a bit of a problem:

It will start fine when cold (ie in the garage when he's going out shopping) however, once he drives it in the hot summer weather and parks, when he comes back to the car he has to crank in like 5 times to get it to start (it will eventually start).

It sounds like textbook vapour lock, but I am not sure where to start in terms of looking for 'common' culprits. Has anyone had any experience with this type of issue ?

Thanks!

Heat-related starting problem can get complicated. As for vapor lock, it's more common in the older fuel delivery system (engine driven fuel pump and carburetor) but is rare on newer ones (tank-mounted fuel pump and fuel injectors)..So the problem can be - electrical, fuel-air, ignition or related components and controllers

Let's do the electrical first:-Check battery voltage (must be >12.5VDC with engine off and >13.8VDC with engine running)-Disconnect the battery connectors and clean them together with the battery poles. If available, spray Battery Terminal Protectant. Reconnect battery and ensure connections are tight.-Check the condition and security of the Fusible Link (Starting/Ignition) usually located in a fuse box besides the battery.Locate the ground wires, clean them, apply dielectric grease then reconnect.-Check the connections at the back of the Starter Solenoid. Make sure they are clean and tight.-Check/clean the single-wire connector to the starter solenoid. Use contact cleaner. if available.

Please indicate if you have manual or automatic transmission. After doing the actions above, please let us know if starting problem still persists.
