Won't start? In this climate, suspect the battery first
A mobile no-start visit in Twentynine Palms, CA runs $95–$150 with a full battery, starting, and charging test; a replacement battery typically costs $190–$380 installed at your address, usually within the same visit.
Everywhere else in America, winter is the battery's executioner. Out here it's the summer: heat above 100°F accelerates the chemistry that ages a battery, boiling off electrolyte and corroding plates from the inside, so a battery that would last five years on the coast gives you two or three in the basin. It rarely announces the damage — it just declines quietly until one morning in an apartment lot off Two Mile Road it delivers a click instead of a crank.
The visit does the honest sequence: load-test the battery, check the charging output, measure parasitic draw. That last one matters for the basin's sitting cars — vehicles parked through a deployment or a long field rotation drain flat and often won't hold a charge again; the test says so before you waste money on a jump that dies by Friday.
If the battery passes, the same visit rules the starter and alternator in or out on the spot — both standard mobile replacements on most vehicles, priced on the call.

When this stops being a driveway job
A no-start from a failed in-tank fuel pump, a seized engine, or immobilizer/key faults is shop or dealer work — and heat-soak fuel-system gremlins on older carbureted trucks sometimes need bench time. Symptoms on the phone sort it in a minute.
Straight answers
Jump or replace — how do I know?
You don't have to guess; the load test does. A battery that fails under load will strand you again this week no matter how healthy the jump makes it look.
My car sat for seven months. Now what?
Expect the battery to be a casualty and budget from there. The visit tests it honestly, checks what else sitting in desert sun costs (tires, wipers, belts), and gets it started or replaced on the spot.
Weekend mornings?
The best time to call — beat the afternoon heat, and it's when the local shops are closed anyway.
