Changed engine and cant remember where the 2 ground straps were located

The strap with 3 ends....connect it to the frame. You can strap the alternator to the block.

Recheck the wiring connections, you missed something.

Look for a missing ground strap from the engine to the body or frame. Remember the engine sits on rubber mounts so that ground strap is essential.

ground straps on engines are either from the battery earth post to the engine or to a body point . If it is to a body earth point the engine earth strap will be around an engine mount. From the engine bolt around the rubber to the body mount bolt. probably on the mount closest to the battery

-ground strap is a pc wire that connect from body frame to the engine.

-Or if ground cable...?The cable that connect to battery's Negative post is the ground.

When you go to an auto store and they give sell you spark plugs they should already be gapped to spec. There is no need to adjust the gap. This may be the reason your car will not start. I would try new spark plugs first then wires. Since the vehicle is a 99 it probably could use a tune up (spark plugs, wires, coils, cap, rotor, chassis lube, and transmission fluid check and flush if needed). Also make sure that the engine block ground strap is in good condition and that there is no corrosion covering the ends of the ground strap. The ground strap is typically located near the firewall and is directly attached from the engine block to the frame of the car.

on some it goes from motor to firewall or motor to the frame.. you have to have a good eye for it is easily overlooked...good luck

there is a special tool to do this, but I just use a giant pair of channel locks

this is true ! Usually the strap will run from either the ground post or sometimes the the top mount bolt , to the body . Look at the ground straps that run from the engine to the frame and engine to body . Chances ar one of these straps are broke . They are located from the bottom behind the engine near the firewall , and on the passenger side of the engine underneath . I had a 2004 venture that the interior and display lights went out , a control module in the dash that ran the display , daylights , and cooling fan went out ! traded it in soon after !!! Good advice !

starter ground/earth strap/cable is normally the cable negative that comes from battery and connects to the engine or where the trans joins engine ? also it may have a seperate strap connected from some location on the chassis and to engine if you trace neg cable from battery you will find where it connect to engine try at point rear of engine? ensue they are clean/secure starter motor takes its ground fro this ie engine--battery
