will not start even when jumping s70 1998

[peterz]

98 s70 would not start but would jump start 2 days ago. battery would not hold a charge so bought a new battery from autozone yesterday. Car cranked fine right after installing new battery.

This morning car would not start even when trying to jump from my truck. It turns over but does not fire.

Low fuel light was on, but no change even after adding two gallons of gas. Still would not start even with a jump.

Any ideas?

Thanks

Three Checks
1. Check for Fuel at fuel rail (Shrader Valve)
2. Check for spark at coil, distributor and plugs.
3. Check for Compression (might not need to go to this step.)

Is your Check engine light on?

If a battery is completely dead, it can keep a car from starting even if the car is jump-started.

A brand new battery needs to be put on a charger overnight before use. They do not come charged from the store. They often have a slight residual charge, but it's nowhere near a full charge.

Take a multi-meter and test the voltage between the two terminals of your battery. Since the battery is new, you should see no less than 12.6 volts, more likely 12.7 or 12.8. If the reading is anywhere below 12.6 volts, your battery is not fully charged.

Also, check the parasitic draw on your battery. It should be, at most, around 0.1 amps (100 milliamps), and that's a high number, the majority of cars should see parasitic draw below 0.05 amps (50 milliamps). If your car is drawing more than this, you have a short somewhere in your electrical system.
